Hello to all, My first post - and if you folks are not too critical it wont be my last. It has been a little bit intimidating reading such professional threads . Here goes my experience on the Rolex.- I have owned 3 Rolex watchs over the past 23 years (Explorer II, GMT Master, Sea dweller) and not one of them kept accurate time (at least not by quartz stds). Matter of fact I have heard the statement made B-4 that the way to tell a Fake Rolex from a Real Rolex is the Fake will keep good time. I will speak highly of their build quality do to the fact that I am right handed and wear a watch on my right arm. This puts an additional amt. of wear on a watch and only the Rolex (of all the many brands I have sampled) takes that kind of abuse . The Rolex watch also has a good resale value and "Mugger Attraction". Or should I say" Status". I would suggest that if you purchase the Rolex than by all means Dive with it, after all they were built Function B-4 Form. Please check into the Bell & Ross "Hydromax"- it is an oil filled watch currently being tested at 34,000 feet. The Hydromax list for about 1/2 the cost as the seadweller. Sorry for being so long winded.
