A couple of very interesting tuning fork watches from the 1970s sold by Solvil & Titus but actually made by Omega.

This is the story:

Solvil acquired cases made by Omega for their F300hz series watches in the early 1970s. They removed the engraving on and in the case back and fitted their own dial with the same Mosaba tuning for movement that Omega uses (but the silver version). This is further confirmed by the Omega crystal (both watches have the Omega logo in the center of the crystal) as well as the filed down crowns to remove the Omega logo (also on both watches here)

These are the two variants of this watch: Stainless steel with blue dial and gold plated with gold dial.

Both watches are in very good condition, probably rarely worn.

Unfortunately, the movements are not working and will need to be serviced.

The cases measure 35mm without crown, 41mm lug to lug, 11mm thick with a 18mm lug width.

They are both equipped with a tuning fork caliber ESA 9162 Mosaba. They are not working. Sold for repair.
