The HMT Rajat has come with us to the land of its birth. If you are ever in the south of India, you might want to make a trip to the HMT museum. https://www.thehindu.com/society/janata-watches-and-braille-timepieces-a-visit-to-hmts-new-museum-in-bengaluru/article29109045.ece If I had known about it last year when I was down there, I would have gone. http://www.hmtmuseum.in/

You could try the oldschool way of vibrating it ontop of a pocket watch. 18000 bph is 150 vibrations a minute, or 25 in 10 seconds. STart the hairspring vibrating just before the second hand on the watch reaches zero and count the vibrations until it reaches 10 second. If your count is less than 25 its too slow, so shorten the spring, above 25 its too fast so make it longer. If you don't think you can count that quick video record it on your phone, use slow motion if necescary and then count them in the play back.

oh never mind it was where i suspected just a little stiff

Thank you!! exactly what I wanted to know

Hi If you can't find them PM me and I will look at this end for you, no problem

From a Valjoux 7734: 2.79mm total length / 0.87mm thread diameter / 1.49mm head diameter These are the screws that go into the case clamps that hold the movement.

We know!!, Or at least have a good idea. Bravo!! Sent from my iPad using Tapatalk

Is the fact the middle dial is for Bombay time, telling us something? I think I'll pass but I am intrigued as to how you set the times for the different time zones as you would need to be able to adjust them independently so you can adjust for daylight savings when they start and end in each zone.

Yes it has. Everything looks rotary, the strap is rotary, the buckle is rotary, the model number is rotary. I believe you can get a new one around £100 mark. Maybe I am just un-experienced with watches younger than 50 years and maybe because it is skeleton and it gives me a different feeling. I made a few pics, this is how I am going to sell some of the watches. I am afraid I have to do that if i am about to continue this nice hobby.

Just finished the overhaul of my Rego Chronostop pin pallet. It has a single jewel, Lapanouse movement. Had to fit a new crystal as the replacement that was on it didn't clear the second hand and was stalling the movement. The dial is perfect for a watch this old. It is officially the LOUDEST ticking watch I own! I kept the old ratty leather band, it kinda adds to the charm. I kind of feel like those old Remington shaver commercials, where Victor Kiam liked the their razors so much that he bought the company.... well, I just bought another one of these on eBay.

From the looks of it,my guess would be the year of the flood.

I think I entirely failed to bid on that very watch. It does look good, but I too am in two minds about what it is. It doesn't look like the very inexpensive Chinese skeletons, but it does look similar, which may be a mixed blessing, since if it is an auto version of the "Chinese Standard movement", you can swap parts from almost any other one, including the non skeletonized versions, with a pretty high level of confidence that they will fit. On the other hand, the quality of these movements varies from extremely good to extremely poor, so your mileage may vary. https://www.ebay.co.uk/itm/001Classic-Automatic-Auto-Mechanical-Wristwatch-Black-Belt-Silver-Shell-wX/202771370401?hash=item2f361d91a1:g:m-YAAOSwRmNdVVvS A quick study of "the cheapest new skeleton Chinese mechanical watch on ebay" (at a mere £5.99 new, shipped from China it is unfortunately £1.95 too expensive to get in to the 404 club), shows some obvious similarities and also some differences. I do have one of those "Winners", a manual wind. These are pretty similar to the automatics. I picked it up used, so it did fall within the rules, but I'm not at home, so I can't provide better pictures for you to compare. There are some not very detailed pictures of it here-> I wonder if it is a "Fake Rotary", a Fauxtary (groan...). Good to see you seem to have brought it back from the dead. Does it have an exhibition case back?

Stepped bezel like the one on that Alpina ? I've talked to my friend and he say he can turn a custom bezel (don't know about a stepped one but I would say he can). He's not a member here but I'll PM you his name and email adress so that you can talk directly with him and see if you can find an agreement. And YES you will have to source and fit a plexi first as the internal diameter of the bezel (and its height too) will depend on that. Have a nice day ...

Thank you for your introduction and welcome to this friendly forum.

Are you sure the balance wheel or staff is not bent? I just cant see any circumstance which would bend a main plate, not saying it cant happen but i would think it would have to be deliberate. Maybe previous owner tried to repair and had fit of rage and slam dunked it on the floor.

That is lovely I’m getting the hang of it but the industrial machines we use try to run away with me. I’m getting the hand stitching sorted and mainly doing repairs taking the load off the main guys in the workshop. My biggest problem is that I struggle to keep in mind the repair is just that. It does not need to be as good as new so I’m spending too much time trying to make it as perfect as I can. I’m learning though and loving it

I have used black epoxy paint (in aerosol) for watch cases etc and it seems to stand up very well for wear. Must allow it to fully cure for maximum hardness/adhesion.

Hi Its a close call on the 66B I Have attached the 66B tech sheet for a comparison 3088_Seiko 66B.pdf

I was going to suggest black stove enamel. It is pretty robust, but heatshrink tubing is a neat idea.

I love that stuff.

All the gizzards

Hmmm ... I could not resist and now I need to think what to do with them? Shall I try to use it with my computer and timegrapher? Or shall I keep them as they are. Science Museum has the complete set: science watch-timers science watch-timer 2

Hi If you can reach the Esslinger site in the USA, Have a look at their tutorials, They have one on fitting and measuring crystals. Probably better explained in words and pictures than I could do here.

Measure the inside diameter of the case as well between 3 and 9,and again between 12 and 6. It is after all this hole you need to fit.

You have 6309 pallets starting at 6€ (plus 3€ shipping) from Speedtimerkollektion, including the cock and escape wheel. https://speedtimerkollektion.com/shop/advanced_search_result.php?keywords=6309 pallet&search_in_description=1&page=1&sort=3a

There are several vids on youtube made by Mark on the various styles and how to fit and measure.

Hi My pleasure thats what its all about cheers
