VSF Omega Worldtimer Movement/Service Photos and Comments *Pic Heavy*

[NaviChief]

I'm servicing a VSF Worldtimer currently and wanted to share some of the teardown pictures.

First up is the beautiful dial and hands. The hands have bevels, and a combination of brushing and polish.

​

Taking the dial off shows a little surprise. There is a clear ring on the dial that lets the 24 hour wheel show through. This is the same as gen construction. The dial is thick, metal backed, and heavy.

The 24 hour disk is press fit on, just like a GMT hand would be. Thanks to skaterluca for the tip on how to remove it. Nice finish work on the plate, which will only be seen by the watchmaker!

​

Here are some view of the jumping hour mechanism. Very important lubrication point here.

​

Nice shot of the cannon pinion and some of the other motion works.

At base this is the 8500/8900 VSF clone movement that is a favorite of mine. Well made, tight tolerances, and goes back together smoothly. Typically it is pretty clean from the factory, and is lubricated, just not well.

​

​

Finally, there was some dirt to be found. On watches like this where no replacement parts are on the horizon, preventative maintenance is the best chance at longevity. These photos are from the autowind and hand winding areas. High stress components.

Thanks for looking. I've said it before, and I'll say it again. I love VSF Omega.


​PS I am not a watchmaker for hire, sorry folks. You've got great ones on this forum already.

Very informative & awesome pictures Sir, thank you for sharing.

The Worldtimer is definitely on my 2022 WTB, so was great to see it stripped down and the underlying quality.

Well wear :thumbsup:

Very good guide! Helped me alot. Did you also service the mainsprings? I mean did you take them apart and use braking grease on the walls ?

Is the outer ring with the city names like Dubai and Dhaka a separate piece that can be realigned or is it a single piece?

Hi, can i ask how you removed the stem?
Just press hard on the stem release button until it releases? Or is there a hidden stem release button under the decorations?

Also, can i ask if it should be removed in winding position or time setting?

Thanks!

Boss, I had a question.
Could you tell me how was the rotor removed?

I believe just pressing hard is what is required. No hidden button or stem

Awesome, thank you. Most helpful.

I love the look of the Worldtimer, but I never would buy one knowing what a ticking time bomb it is. I was under the impression that no watchmaker would touch a rep with a 10-foot stick. Your post was quite eye-opening. Thank you!
