I already owned a promaster diver but want a model that I could wear as an everyday tool watch. My attention was drawn straight to the promaster super titanium range. After browsing the range of models my attention was drawn to the limited edition whale shark by it's starkly different look and design. The watch is 47mm but doesn't wear that big in practice due to no lugs being incirp into the design. The dive strap it ships with is good and comes with a further extension. I have always preferred NATO straps for comfort and security and fitting one to this model makes it less cumbersome around the wrist. I would recommend this watch, it's very lightweight due to the super titanium and very durable. The lume is legible after many hours and the case we'll protected by the design.
