The Invicta Men's Russian Diver's watch is a big, solid, well made watch backed by a very good warranty.  It is a nice looking watch with large, easy to read numbers and luminous hands (important in a diving watch).  The feature which I find most attractive is that is it not merely "water-resistant" but water proof, and to a greater depth than most.  For me this is an important feature, as I live essentially in the rain forest, on the windward side of Oahu, where it rains more often than not and has humidity close to 100% the rest of the time.  It is an environment which is not good for anything mechanical or electronic if it is not sealed.  At this point I have a fair bit of experience with the brand, as everyone in my family has one.  We purchased the women's automatic four our daughter and my husband and son each have the men's (all divers).  Myself, I prefer a slimmer profile, lighter watch.  Note, this is ENORMOUS, the largest watch I have ever seen).  All that said, we have not had problems with any of them despite the fact that my husband goes out for cardio walks rain or shine (and it does rain.... a lot!)

The watch is well constructed and made from high quality materials: a Swiss movement, mineral quartz crystal and sealed stainless steel case.  Even the rubber band is more substantial and feels nicer than most.

I gave the watch 4 stars rather than 5 because, as I noted, I prefer a slimmer profile.  However Amazon details the dimensions.  If you like big chunky watches, then for you this would be an asset rather than a liability.  I also prefer the automatic movement, particularly in a divers watch (or any sealed water-proof watch).  Usually changing the battery compromises the water-proof quality (most manufacturers state such).  When you purchase through Amazon a card is included to upgrade to platinum service and/ or extend the warranty.  Invicta recommends returning the watch to them to have the battery changed (or for any other required service).  None of the watches we have has required service, or a new battery yet (the automatic being the oldest, but one which does not require a battery).  It is possible that Invicta services them in a way which does not make them less water-proof.  They do state that they test every watch thoroughly for 3 weeks before returning it, so I would imagine that is part of the testing.  I may well not know for several years (depending on battery life) but thus far all are performing nicely and have not required service either for any kind of inherent problem or for problems caused by the environment (which is remarkable in and of itself).

I will add that it comes nicely packaged in a presentation box, making it emminently gift-worthy.
