Case: 42mm Stainless Steel. Water Resistance: 300m. Crystal: Sapphire. Dial: Blue. This includes dropping, banging, or use past the manufacturer’s specifications. In the event of manufacturer defect, you may take your watch to any authorized dealer for repair.
It came in complete package with all stickers and protective films. The accuracy of the watch is -1 sec/day, I expected +, not -, but it is pretty accurate. I do like this Seamaster 300 with blue dial. It fits any cloth styles. I changed the stainless steel bracelet to blue rubber strap. It is much lighter and very flexible.
Omega Seamaster is one of the nicest watches for the money. I can’t understand the lure of Rolex, when Omega knocks it out of the park with this beauty and about half the cost. You can always find something to not like about watches, or anything for that matter, but on this they are far outweighed but all the nice things about this watch. Stylish, comfortable, timeless, refined, great lume, and on and on. Love the scalloped bezel, as it looks better and slides under a shirt sleeve much better without fraying the cuffs. The helium escape valve isn’t necessary, but is part of the identity of this model. I will never have a need for it, but it doesn’t bother me nor does it get in the way or make the fit uncomfortable. The bracelet is the most comfortable I have worn and doesn’t pull my hair, which I have a lot of. Style, quality and value you can’t go wrong.
Amazing piece.  excellent quality for the price, iconic timepiece and very versatile. The blue basil is phenomenal and outstanding. can’t beat the METAS certification
