Outside of the case back marked with black sharpie ‘354’. Original, blue prototype dial, with white printing. Raised silver coloured hour indexes. Raised, silver company logo at ’12’.

Movement: SSIH 5500, battery #344

Dimensions: Diam.: 38.5, lug – lug: 41, strap width at lugs: 19mm

Strap: Generic blue strap, generic stainless steel buckle.

Additional Info: This watch is extremely rare, only 2 of these prototypes are known. This watch contains the first in-house movement developed by the SSIH-Quartz division founded in September 1974. This movement was later mounted in Tissot watches as cal.: 2030. The time setting is precision oriented and very fancy (see instructions below). Omega never used this caliber and never used this exact type of case. The design of the prototype dial was adapted to/from other Omega prototypes (never for production models), the case has never been used for other pieces. The other known prototype of this version will be featured on Omegaprototypes.com.

Setting the time:

• Precision sync: Press the crown to stop the seconds. Release when in sync with reference time.
• Set hours: Pull the crown to set the hours
• Set minutes: 1) press the crown to stop seconds; 2) hold crown depressed for 5 seconds; 3) release for a fraction of a second; 4) press crown again and hold until the hands rotate to the desired position.
• Set date: No quick date feature. Pull the crown to set hours, turn slowly passed ’12’ until the wanted date is reached.

Provenance: This watch was obtained from the former Omega watch designer Raymond Froidevaux, who among other models designed the famous Omega ‘Albatros’ of 1976.

Price: 1250 CHF

Additional Info: This watch is extremely rare, only 2 of these prototypes are known. This watch features an in-house movement developed by SSIH to counter the almost imminent bankruptcy of Tissot in 1977. It is a very simple, but robust automatic movement containing several plastic parts. Tissot used this caliber in several models starting from 1977, but none of these models took up the design of this watch. The dial design as well as the case design are unique to these prototypes. The other known prototype of this version will be featured on Omegaprototypes.com.

Provenance: This watch was obtained from the former Omega watch designer Raymond Froidevaux, who among other models designed the famous Omega ‘Albatros’ of 1976.
