I have been collecting and restoring these machines since 1970. david

There was one thing you forget to mention on your video JD. When you are machining a shaft to a specific diameter or machining a plate to a thickness, set the size on the micrometer first then zero the micrometer at that size. When you do this and take measurements, you can read directly the plus or minus relative to the size you want. It save you doing a wee calculation to get the correct amount of metal to remove. Also when used as I gave described it makes a great comparator for checking the sizes of batches of things.

Just recieved my 0.001 accuracy digital micrometer from Aliexpress.com and it works like a charm. Sent from my iPhone using Tapatalk

I usually use finger cots when I'm reassembling a movement and casing it. Fingers shed dead skin and oil, don't want that in my movement after I've gone through all the trouble of cleaning it.

I wouldn't advise opening it unless you have the correct tool for the job. It is a very delicate piece that is beautifully engineered and would be easy to damage as the parts are screwed together tightly. The first one I worked on was cleaned in my ultrasonic bath still assembled. I then managed to carefully get 9010 oil into the internal gears with a very fine oiler. Far safer to fo this than risk damaging an irreplaceable part without the correct tools. That watch has now been running everyday for the last couple of years and keeps well with chronometer specification. Regarding the rotor, I can't give you the answer you want, but if it is clear of the movement and running smoothly I would leave it.

Sorry, had written a post but tried to delete it as I misread a previous post. It's all good ☺

I wear a pair of latex gloves for reassembly even tho I don't touch any parts by hand until I fit the dial , hands and 're-case.

Sorry off topic...my bad...

Fingercots on left hand. Index finger and thumb. But usually only when i put the last parts that i need to hold with my fingers.

Looks good, I'm afraid folks who ask might be disappointed when I tell em it's not a you know what! Although these days most people don't ask what I'm wearing! thanks you just drove me one step closer to buying...I have a few lines in the bay on a Seiko 6139 Navigator timer or so the advert says, may be able to steal it, so have to wait a bit.

Ooops don't know what happened there! First time I posted it said "Failed to connect to server" Obviously not. Anyway this is what my Invicta looks like on the wrist Sent from my SM-G920F using Tapatalk

I agree with Geo, if you don't have the tool then our methods work fine. Mine has now been running for over 2 years since serviced and still keeps 4-5sec/day (not tried to better this as more likely to make worse!!) and auto-winds with no problems. I wear approx 14 hrs/day and it is static dial up for the other 10hrs. Even had periods of up to 2 weeks when not used and after a short manual wind all is fine again. The rotor bearing pivot/plate is available and not too expensive. Don't know about the bearing in the rotor itself if that's worn, whether it can be replaced or if a complete rotor will be required (likely to be quite expensive).

I thought these photos would turn a head or two. I'd like to know what's in the Leica box!

Nice piece of kit Jd I am in the process of acquiring some measuring gear of my own. That digital micrometer would complement my recent digital calipers purchase nicely. I am also looking to purchase a Fientaster (spelling) since the calipers are a bit crude for fine measurement. Mine are brand name and made to a DIN 862 specification as well as the company specs. The problem with made in china is when they deviate from the manufacturing standards imposed by the large corporations that use them to produce goods at price point. China is capable of producing some very nice stuff. Too bad the majority of its goods are on par with made in India... While lacking the resolution of Jd's micrometer I am happy at .01mm with excellent repeatability. And before I get flamed for measuring a pivot with calipers, rest assured this was a broken staff and I was curious as to the calipers ability and accuracy. The build quality of the micrometer certainly looks to be excellent from the video, and the price is right...

well they are just plate jewels. i think the hamilton jewels were burnished in the settings. new jewels are friction fitted. so you will ream out the setting with a jewling kit and press in a new one. you will need to know the pivot size and the diameter. so measure the pivots first then order a diameter a little bigger thanthe old hole. your ream # needs to match the jewel diameter. then you just press it in. if you give me the measurements i can look on my seitz chart for a #

Jguitron - Before you put the hands back on the watch, did you advance the winder / time until the point when the date just clicks over to the next day? If you did not do this part, the position of the hands will not be synced up to midnight.

Reads like the Danish postal service ! They slashed the number of mail-boxes by 60%, empties them instead of daily, only on Saturdays and Wednesdays and they doubled the postage cost. A picture postcard to Britain (or within the EU) cost now (2016) close to £3.- !! Wait for it; a raise is due for 2017 ......... If this is indeed the magic trick, I will see my boss, cut my work week by halve and ask him to double my salary ! Better still, work one day and quadruple my salary !! Gosh, I never thought about this one before ..........

There is an Advent calendar giveaway at NOMOS Glashütte where i was winning the day 7 surprise item... a super awesome professional antique steampunk Eibar el Casco pencil sharpener... which actually belonged to the company's founder, Roland Schwertner Sure i made a video of it.

I've just watched that video above, it should be "X" rated!
