2257.80, Royal Navy Clearance Diver Seamaster 300, Steel
A scarcely seen Seamaster 300 made for active members of the Royal Navy’s Clearance Diving unit in 2010. The unit’s crest is set under sapphire on caseback, a numbered series of 150 watches. The run was never publicized. The rest is standard late 2000s Seamaster 300: electric blue wave dial, 41mm steel case (that wears remarkably thin), and calibre 1120. Full set.
