Seiko Prospex Marinemaster SJE 117
Iconic Seiko Marinemaster compared to the SPB 451 in blue. Where the SPB leans in to the heritage, the MM is a little more blingy. OOPS! I did say MM 300, when this is only WR to 200, so the 300 moniker just can't be correct. Polished on the bracelet, more pronounced bezel teeth, and a coated steel bezel insert instead of aluminum. A big difference is the engine... the MM has the 6L37 with stated accuracy of -10/+15 vs the -15/+25 of the SPB. Will track it and report back. Great watch, not sure (yet) if it is worth 2x the SPB.
