This is one of the things I love about old mechanical watches, something that's often older than us still ticking away whilst being bounced around on your wrist. I think this is why I tend to see quartz watches as a bit soulless.

Hi You will probably find these tech sheets useful doing the V7733 . all the best 1060_valjoux 7733, 7734, 7736 Pages 1-5.pdf 1061_valjoux 7733, 7734, 7736 Pages 6-10.pdf 1062_valjoux 7733, 7734, 7736 Pages 11-15.pdf

It's fixed. A little bit of solder and heat shrink and I'm back in business. Thank goodness because I don't have the money to spend on tools or watches right now.

Not all hairsprings are produced in Switzerland China and India must have domestic production of hairsprings, and this British firm manufacture custom made Hairsprings and carry's a large range in stock. http://www.britishprecisionsprings.co.uk/html/custom_springs.html

How can you contact an hairspring producer. There are only like 2 or 3 in Switzerland and they don't correspond with repairers or individuals.

Thanks guys!

How on earth did you acquire this much info about the watch history in that time?

This is a French make of watch and probably has something like a Lorsa 238 in. I suspect 'Avystyle' relates to some kind of marketing exercise as your watch can be found with other names such as 'Spa', 'Montres de Besancon' and 'Sablier' as per the montage below! In terms of cleaning I would not recommend it. This would have been at the cheaper end of the watch hierarchy and the dial a thin piece of brass on to which the design would be printed with non-durable paint. Start cleaning and almost certainly you'll find the paint will simply rub off! How bad actually is the dial?! It doesn't look that bad and whilst you could certainly get rid of any loose lint type dirt gently it could be that after a nice case polish, and even a brand new shiny crystal, you keep it as is!

That is good to know.

Gentle press on tweezers just to hold a piece, excessive force not only ruins the tweezers but you get lots of pieces ping off. You ahould streigthen the bent and then dress the tweezers, lay a fine grade sand paper on top of flat glass, stroke are to be away from the tip of prongs. A good and properly dressed pair tweezers lets you hold an endstone on the premeter without the ping off. That is both prong keep staying aligned as you hold.

Contact Jan the bench guy and ask for a Dumet B#1 tweezers. Made of phosphor bronze and much sturdier than common brass tweezers.

They do bend. I keep my brass tweezers pretty round and short. Not the sharp as i do with other tweezers. I use them for bending up parts to . I use a diamond plate i bought on cousinsuk for dressing them. Also use some wet and dry paper. https://www.cousinsuk.com/product/diamond-stone

Best to contact the hairspring producer. Years ago you could get charts for this sort of thing. These days I think it is beyond most watch repairers.

The serial number points it to ca. 1945. Omega bumper automatics were either from the 28.10 or 30.10 series at the time. The designation is on the base plate underneath the balance wheel. The dial seems legit, no redial. So, there's no reason to assume that the dial has been swapped.

The jump hour above Yankeedog? Surprisingly fewer than I expected, only jumpers and clicks for the date and hour wheel. The minutes is directly driven from the equivalent of the cannon pinion, (this being a pressed fit centre wheel) and then the sweep seconds as normal. You can see the innards of it here. I had no intention of filming this one as it was my first jump hour and I wasn't certain what to expect but the difficulty removing the centre wheel led to the video which is a bit choppy in procedure due to the above reasons. If I get another I'd enjoy doing a proper strip and service video. https://youtu.be/Dfi_z19317s

This 1967 classic Timex accompanied us when we went out to the cinema with friends tonight.

Ha!! [emoji851]. I’m from Texas. I was actually thinking there was some kind of gray market cowboy boot traveling show of which I was woefully unaware! Thank you for helping with my English! It does sound like fun. Sent from my iPad using Tapatalk

That screw is to change the dept of the pallets against the escape wheel.

Recently I had to do small pushers springs. I used spring wire which diameter was 0,2mm. Couple attempts and springs fit and work well.

Don't forget to connect the motor case to the grounding conductor!!! Frank
