Actor George Clooney spotted wearing a Omega

Lake Como or a Mediterranean bay — the setting is unmistakably Italian, and George Clooney is relaxed aboard a vintage Riva runabout in a striped linen shirt. On his left wrist sits a watch that could not be more different in character from its surroundings: the Omega Seamaster Ploprof 1200M, one of the most architecturally extreme dive watches in production.

The Ploprof — shorthand for 'Plongeur Professionnel' — traces its lineage to 1970, when Omega engineered a purpose-built saturation dive tool for professional use at depths that would crush conventional sport watches. The modern 2009 reissue honours that DNA faithfully. The 55mm × 48mm asymmetric steel case houses a unidirectional rotating bezel secured by an orange pusher that locks the bezel against accidental rotation — a functional mechanism that also doubles as the watch's most distinctive visual signature. Water resistance is certified to 1,200 metres (120 ATM), backed by a helium escape valve at 10 o'clock.

Power comes from Omega's Co-Axial calibre 8500, a movement that represented a watershed moment for the brand when introduced: a proprietary escapement designed in-house, offering reduced friction, improved service intervals, and chronometric performance that earned COSC certification. The movement beats at 25,200 vph with a 60-hour power reserve. The black dial visible in the image, with its applied luminous indices and bold chapter ring, matches the reference 224.32.55.21.04.001 specification — steel case, black dial, rubber strap with titanium deployant.

For collectors, the Ploprof occupies a singular niche: it is too large and ergonomically demanding for most dress occasions, yet it is precisely that uncompromising nature that earns respect. It sits alongside the Rolex Sea-Dweller and Blancpain Fifty Fathoms X Fathoms as a serious tool watch that carries genuine engineering credibility rather than borrowed diver heritage.

Clooney has been an Omega brand ambassador since 2008, but his choice to wear the Ploprof — rather than a more photogenic Aqua Terra or Speedmaster — signals genuine appreciation. The grey market currently prices this reference modestly above retail, reflecting steady rather than speculative demand: a collector's watch for people who actually know what they are buying.
