Story
Awarded in 1976, this Omega De Ville chronometer captures the brief, fascinating era when electronic tuning forks represented the pinnacle of horological accuracy.
Maker / Origin
Unattributed · Omega SA, Biel/Bienne, Switzerland, Mid-1970s Space Age
Condition & Value
Because tuning fork movement parts are largely obsolete, the watch's value hinges critically on its ability to hum and keep time, with corporate engravings acting as a slight market detractor. The case and gold-filled bezel show light, honest wear consistent with age.

Market Analysis
Direct comparables for standard stainless steel or gold-capped Omega De Ville f300 Hz watches show a highly bifurcated market based entirely on operational condition. Fully serviced, functioning examples reliably clear between $800 and $1,200 at specialist dealers. Conversely, unserviced or non-running examples (such as a Ref. 198.0035 sold at Alexandre Landre for $340) drop to a $300 to $450 floor due to the severe scarcity of tuning fork replacement parts. The presence of a corporate presentation engraving ('Morimasa Fukui | E. Countryman Award 1976') cements the era provenance but generally narrows the buyer pool, requiring a 10-15% downward adjustment against pristine, sterile casebacks. The current FMV assumes a standard steel or gold-capped case in working, but unserviced, 'watch-only' condition.
Value Drivers
▲ Chronometer-certified f300 Hz tuning fork movement featuring a completely smooth sweeping seconds hand
▲ Documented 1976 timeline provenance via the 3M Company E. Countryman Award engraving
▲ Rising niche collector interest in 'Space Age' 1970s electro-mechanical horology
Concerns
▼ Unknown operational status of the tuning fork movement; repairs frequently exceed $500 due to scarce, obsolete parts
▼ Unknown case material (stainless steel vs. gold-capped) and unknown dial originality
▼ Corporate caseback engraving typically acts as a 10-15% value detractor on the open market compared to pristine casebacks
▼ Assumed 'watch-only' condition without the original Omega box, guarantee papers, or factory bracelet
Best Venue
Chrono24 or specialized vintage watch forums (e.g., OmegaForums), where niche collectors actively seek functional 'hummer' references and understand the nuances of the 300Hz movements.
Upside Potential
If the case is verified as solid 18k gold rather than steel or gold-capped, or if it retains an original factory integrated bracelet and original presentation box, the value could easily exceed $1,200.
Authenticity Notice
Medium risk. While complete fakes of f300 tuning fork movements are extremely rare due to their specific electro-mechanical complexity, 'frankens' built with mismatched dials, hands, or aftermarket cases are common. A watchmaker should verify the movement caliber and the reference number stamped inside the caseback.
