an actual Corum 138-181-20-0001-BA44 Men's watch prototype

Last week we showed you a Rolex that featured a Louis Cottier engineered world-time movement, and now we're here to show you an actual Corum 138-181-20-0001-BA44 Men's watch prototype that has never been seen before.The Rolex Divomet was an in-house designed diving meter with the purpose of reading the depth of oceans or lakes; one hand indicating the feet 10 by 10, the second hand showing the relevant feet.A bracelet passes through the circular crankcase which contains the mechanism as found in a Bourdon manometer.

One thing of note with these floating cosmograph Daytonas is that the sub-dials are actually subject to corrosion far more easily than your replica Breitling Windrider Chronomat Evolution average Rolex.That said, this one appears to be in excellent condition.Our friends at 10 Past Ten Timepieces (who have a really knock-out inventory of Rolexes, btw) are asking $17,000 for this particular example.We think the price is fair, especially for such a unique Rolex.

The Divomet, we are safe to assume, was developed in hopes to be used by Jacques Piccard and Donald Walsh in their descent in the Trieste to the deepest Corum 138-181-20-0002-BN42 Men's watch known point on earth (the Mariana Trench in the Pacific).There, they used the Rolex Deep Sea Special strapped to the outside of the bathyscaph.The Rolex Divomet never made it out of prototyping and was, up until this very item suced, totally undocumented.
