    ETA GMT movement?

    To quote the late Patrick McGoohan in his futuristic series, "The Prisoner", "That would be telling".

    ETA GMT movement?

    And exactly when did necessary enter into a reason to purchase yet another watch when we already have multiples? As old fashioned as it sounds, I use my blinkin' phone for just that. Any social networking is still done the old fashioned way, one handshake at a time while making eye contact. If I allowed need to dictate my watch purchases, I would still own one Timex watch. Yeep! I just took an quick inventory and I'm far too embarrassed to post that number publicly.

    My watch collection

    Lovely!
  4. All computers have a clock. And since it's usually a CMOS (complimentary metal oxide semiconductor) with no real attempts to make it all that accurate, it usually isn't. The windows operating systems prior to W-10 have the ability to set the time and date as well as choose your time server. However, the frequency of syncing with the time server of your choice, is not a user defined value. Windows sets it by default at 1,036,800 seconds or, 1 week. Your CMOS clock is free to be totally inaccurate in between sync events. The only way to change this is to edit the registry on your computer. Not everyone cares to muddle around in the registry because bad things can happen if you muck it up. However, if you go to www.worldtimeserver.com/atomic-clock/ you will find a very small applet that is free to download. It's only 891kb so it's quite painless. It adds the ability of a user, with administrator privileges, to easily set the sync time to a more useful pattern. It will also allow you to connect via the internet to the NIST (National Institute of Standards and Time) in the US and allow your computer to become in essence, a repeater for the Atomic Clock which has an accuracy of -1 second every 400 years. The file you will need is AtomicClockSync V3.5 and it adds absolutely nothing to your computer in the way of programs. It is merely an applet that edits your registry for you. I've tried it out and it is both virus free and correctly written. Further, you can save the applet on your computer. I placed mine in a folder aptly named, Atomic Clock, and set my sync value at 1 hour, or in my case, 3600 seconds. Now, anytime my computer is on and I'm connected to the internet, I'm automatically synchronizing with the NIST every hour and I know the correct time when I'm setting a watch or measuring accuracy. Should I feel the need, I can access my folder and relaunch the applet to change the sync frequency any time I choose. Cheers, Don

    Rolex case back opener

    Sorry that the link didn't work. The opener comes with a bar style wrench and 6 different dies to fit Rolex and Tudor style backs for less than $20. You should be able to search using those terms in the original link if you have any interest. If not, then I hope your toothed pins allow you to open your watch. Keep us posted on your progress, please.

    Rolex case back opener

    Have you seen this tool? www.ebay.com/itm/Fine-Watch-Repair-Tool-Back-Case-Opener-Cover-Remover-for-Rolex-Tudor-shus/183492246412?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649
  7. I've always enjoyed using tools and usually, but not always, I purchase the top brand. A case in point was my auto repair tools. Rather than use Snap-On tools, which are so pricey they will bring tears to your eyes, I opted for Craftsman tools instead. At one time, they were sold by Sears and their guarantee was the best in the industry. I've never tackled a chore on an automobile where a Craftsman tool failed me and I've done everything from frame up restorations to an automatic transmission overhaul. With watch repair tools, so many of them are highly specialized and brand specific. Watches are both a passion and a hobby for me so I don't have the tool assortment that a professional would. With screwdrivers though, I felt there had to be a middle ground between cheap junk and a set costing the equivalent of a mortgage payment on a house. So, with that goal in mind, I purchased these: www.ebay.com/itm/Optician-Rotating-Stand-With-9-Pcs-Screwdriver-Set-Kits-Tools-Watchmaker-Repair/372338243981?hash=item56b116b98d:g:KXoAAOSwcu5URa-O:rk:1:pf:0 They're surprisingly well made, comfortable to use and feel exactly weight enough in my hand. The replaceable tips, are utter garbage. So, I purchased these: http://www.ofrei.com/page239.html Now the business ends of my screwdriver set sport Bergeon bits. Total cost, less than $35 USD for the screwdrivers, holder and new bits. The tips are what do the real work so I'm good.

    Raymond Weil 9514.5

    It's Swiss. What else can you expect? I did fine an original 556.031, new, listed on the US version of fleabay for $400. Ouch! The seller must be assuming that someone wishes to restore a valuable heirloom.

    Seiko S-261 opinions?

    This is little more than an inexpensive copy of the Seiko S-261 and won't work any better for you. Most of the Seiko snap on water resistant models that I've owned all have the indention on the back placed between the lugs. You need a removal tool that is capable of working between the lugs and this one won't do it. At least not properly. You would have to clamp the cast too high in the tool in order to access the area between the lugs and the watch will pop out of the holder instead of giving up the case back. Even if the small removal indention is on the side, every Seiko repair manual that I've read cautions to place it between the lugs when reinstalling the back. Your watch may or may not be a JDM version. Usually, JDM versions were sold only in their Eastern markets, mostly in Japan. However, many US sailors purchased watches when on a western Pacific deployment over the years and these watches have slowly found their way into our domestic supply chain. My general rule of thumb regarding JDM models is to ascertain whether or not the model was ever sold in the US at retail. The 6119 movement was a real workhorse in movements sold to the US markets so what you may have is a Japanese version of this watch with the Kanji week wheel. The wheels aren't plentiful. Indeed, no spare parts for this caliber are in good supply but other calibers shared some parts so thankfully, restoration is mildly difficult but certainly not impossible. There is currently one Arabic week wheel for this caliber listed on our favorite auction site but it's a bit spendy. Were it me, I would leave the wheel and learn the Japanese day characters. There are only 7 of them and Sunday is a gimme since it's in Red. Vive la difference, eh?

    Seiko S-261 opinions?

    Ultra tight snap on case backs are a pain. Literally. I have a Bulova that is also very difficult to remove. In fact, I've never been able to open it with a case knife. As posted above, the Seiko S-261 is an expensive paperweight. I purchased a tool very similar to this: www.ebay.com/itm/New-Type-Watch-Repair-Tool-Snap-on-Watch-Back-Case-Opener-Workbench-Case-Remover/264127322090?hash=item3d7f3717ea:g:yQcAAOSwY4pZZufe:rk:79:pf:0 I'm not shilling for any of the sellers of tools here, just mentioning what worked for me. There are better prices to be had also than the one in this link. I'm already assuming that you've thoroughly examined the case back to see if there is a slight indentation on the case back lip. If so, that's where you apply pressure. Does the case back on your 6619 say waterproof or water resistant. If it says "proof" then it's a 1966 vintage. By the 70's, the US Federal Trade Commission, among others, had forced manufacturers to adopt the totally asinine system in use today and your watch would say, water resistant. Somehow in the new system, 200 meters on the dial doesn't necessarily mean that it's safe to dive into the deep end of your own swimming pool while wearing it. Washing your hands with it on "might" be okay. You've got a great watch with your Seiko 6619 so don't give up. Once you have a proper case back opener for this type of watch, you'll wonder how you ever did without one. Expect to have to press the case back on when you've completed the repairs too. You almost certainly won't be able to do it without dies and a press.
  11. Please, anyone, feel free to post photos of your own work space here. Perhaps I should have titled the topic "Show us your work space for watches".
  12. I've been putting together a small work area that I can use when I'm in the mood to work on a watch. It's nothing fancy but I do find it both comfortable and useful. The table is a repurposed computer desk that I moved from the bedroom since I no longer keep my laptop there. The chair is an original 1930's oak swiveling office chair with arms. I rescued it from a print shop that was going to toss it out close to 15 years ago. It needs refinishing but as it's older than me and I'm not in line to be refinished, it'll have to do as is. The lamp is a Dazor 2324 articulating twin tube desk lamp that puts out quite a bit of light. I'm currently awaiting a response from the manufacturer about whether or not they offer a kit for converting this lamp to LED lighting. If not, then I'll collect up the pieces that I need and do the conversion on my own. The US is going to phase out all fluorescent tube production in the future as the bulbs contain Mercury and are an environmental hazard. I've already converted all of my other lamps in the house so this one will be the last. Various watchmaking and repair tools are stored in the desk. I don't really have that many tools as this is a hobby enterprise for me, not a real vocation. I've learned so much since becoming aware of Mark's videos and joining this forum. The watch on the desk is a Seiko solar powered dress watch. I don't wear it all that often so I'm letting the lamp and the natural light from the windows charge it up.
  13. While out shopping last week, I stopped in at my local Goodwill Industries store and browsed their watches. For non-US residents, Goodwill is a business that provides work training and employment for handicapped individuals. They fund a lot of their programs by accepting donations of everything from clothing to furniture to jewelry and then selling it in one of their stores. It's a great place to pick up an odd bargain plus, it helps the community. I was delighted to spot a Seiko perpetual date 8F32-0019 on display. It was offered for $21 as it wasn't working. It hasn't been two weeks since I viewed Mark's excellent YouTube video about how to change the battery in one of these watches, then reprogram it. I bought it and brought it home. To begin with, this particular example was manufactured in May, 1998 which places it near the end of the product cycle. That caliber has been discontinued for some time now. This particular watch was a game premium at the Big XII football championship which was sponsored by Dr. Pepper, a soft drink brand. They were given to each team member, coaching staff, trainers, important alumni, etc. What makes this one unique is that it was never worn. That's right! Whomever receive it placed it on a shelf in the closet where the battery (10 year battery life on this model) died and the watch lost its program. It was donated recently to Goodwill where I found it. I replaced the CR2014 coin cell battery, then reprogrammed it according to Mark's instructions. Thank you Mark. The inside of the watch was basically untouched. At some point, the company that supplied the watches to Dr. Pepper removed the original dial and replaced it with the commemorative one it now sports. The only other issue noted was the date changed at 9:30 each evening instead of midnight. I suspect that whomever replaced the dial didn't bother to properly set the hands when reinstalling them. Additionally, the sweep second hand was off by half the width of 1 second. I corrected those by removing and properly reinstalling the hands. Were it not for Mark's original video, I wouldn't have had the knowledge to buy this watch, replace the battery, reprogram it and reset the hands. This is an absolute little jewel of a watch. Additionally, since it operates at 196 Khz instead of the more usual 32768 Hz, these models are incredibly accurate. The factory spec for a model of this type that is worn 12 hours/day is +/- 10 seconds/year. Wow!

    What makes a quartz watch "tick"

    Not to put too fine a point on the operation but actually, the 'divider' is a frequency counter or as I was taught when I received my US Navy electronics training back when knights still wore armor, a ring counter. Why was it called that? Because it literally counts every every frequency vibration and then overflows to the next counter in a ring pattern. It is a 16 position counter but the 16th position is the output so it's actually 2 ^15 which equals 32678. When the 15th register fills up, it sends the next pulse to the 16th position which sets a 1 and feeds it to an amplifier that drives the stepping motor one notch and zeroes the counter for the next cycle to begin all over again. One of the inventions which made modern miniaturized quartz watch circuits possible was the invention of SMT (surface mount technology) 16 position ring counters. You are correct in that it is much more common (read less costly to manufacture) in a modern watch to find a circuit without a trimmer capacitor. The crystal instead is usually set to operate slightly higher than 32678 hz, then inhibit pulses are programmed from the cpu to delay the stepping motor thus correcting the accuracy. Quartz watches can get a bit technical where the electronics are concerned but they are truly marvels of engineering and inventive designs every bit as much as mechanical watches. Constant temperature helps immensely when it comes to stabilizing the frequency of a quartz oscillator. That's the main reason why the more you wear a quartz watch, the more accurate it becomes. Your body heat is the stabilizing, temperature compensation.
