For many collectors the holy grail of the tool divers. This MarineMaster 300 is the last model from Seiko with the MarineMaster sign on the dial instead of the X. Also this model has the DiaShield Case and Bracelet coating, the Grand Seiko 8L35 automatic movement (Hi-beat 4K, 26 Jewels), and Dual Curved glass with anti-reflective treatment.

Full set with an extra Crafter Bleu rubber strap!
