Theres simply no way around the fact that this watch is gigantic. The ProDiver has a huge 51mm case diameter and is nearly 2cm thick - definitely not something that will fit under a shirt cuff. This watch is so large that even the big Rolex Deepsea (ref. 116660) starts to appear small when sat next to the ProDiver. Although the ProDiver is only just water-resistant to a mere 1000m with the Deepsea enduring the far more sensible and useful depth of 3900m, I think the ProDiver would be sufficient for the 99.9% of divers.
This is the new Moonwatch for the space race lovers who may not be able to afford an original pre-moon 105.012 or post-moon 145.012 Omega Speedmaster, being tested and certified by NASA to endure extremes in temperature, humidity, shock, pressure and vibrations. But unfortunately for some, these rare gems of timepieces also command a high asking price on the second-hand market. Costing 3 or 4 times that of the Speedmaster Professional Moonwatch I'm currently reviewing here (released in 2014). Or this watch could be suited to those who don't want the hassle of buying a second-hand original. What with finding one in a good condition, with a service history, from a reputable seller, at a good price.
Throughout wristwatch history Rolex have forever been at the forefront of innovation. They are known as the first major manufacturer of a completely water-resistant divers watch thanks to a series of landmark publicity stunts to promote their brand. They put another mark into the history books with the Datejust that automatically adjusted the date by itself - an unheard of accomplishment at the time. And they are also attributed with the first watch to show two-time zones with the GMT master.
