In a world of oversized watches, the Omega Seamaster Professional midsize is a smart choice for a pro dive watch with a manageable size. You get everything from the larger SMP version, just in a smaller package: Automatic movement with chronometer spec, iconic blue Bond-style wave dial, blue uni-directional bezel, the classic SMP diver’s bracelet with wetsuit extension, helium escape valve – where else can you get this serious of a timepiece in a 36mm form factor? The 2551.80 was produced between 1993‑2004. Without the original dated card, KTT is not sure precisely when the piece was produced, but we do know that early versions of this model were equipped with the Omega caliber 1109. The watch listed here appears to be a later version with the upgraded caliber 1120.
