Omega Ploprof Prototype: Unveiling the Early Development of an Icon

Key Points from the Discussion

• Early Ploprof prototypes featured various case, movement, dial, and hand configurations for testing, including plastic or steel locknuts and different caliber movements (1000, 1001 with thermal compensation, and the production 1002). The existence of black dials is debated, with some suggesting they were early color tests while others believe blue dials simply discolored over time.
• Omega can confirm a watch's original movement, sale date, and location via an extract, but not necessarily the original dial color, though it usually aligns with the era. Service cases also have distinct internal markings.
• The market for vintage Ploprofs, particularly SHOM models, is complicated by the release of authentic parts to third-party vendors, leading to a proliferation of 'put-together' watches. An Omega extract of the archives is crucial for authenticating these pieces.
• The original Ploprof is surprisingly comfortable on the wrist compared to the 1200m reissue, despite its robust size. Some prototypes have specific markings on the caseback, indicating their experimental nature.
• The unique case shape of the Ploprof means divers do not need weighted belts to wear it. The 'baby brother' SHOM model also features a distinctive case design.
