Hi All...new member here...first "technical" post. I've researched the PlanPro mods for 2254.50...wondering if the same PO bezel and crystal can be fitted to the Seamaster 300M Chrono Diver and have the watch retain its waterproof rating? 2254.50 (stock and w/ PlanPro mods) Also...if the mod is possible, does it make a difference whether one starts with 2594.50 or 2594.52 (one uses 3301 movement and the other 3303 movement)? http://www.omegawatches.com/watches/seamaster/300-m-chrono-diver/25945200/ http://www.omegawatches.com/watches/seamaster/300-m-chronometer/25945000/ I did a quick search for "2594.50 mods", "2594.52 mods"...found nothing. Thanks for your expertise.
