Why We Love This Watch

Gorgeous from any angle, (the front speaks for itself with a unique hand set, or check out the deep oil pressed illustration on the back, or the curved case sides with a mix of brushed and polished finishing and dual gnurled and decorated screw-down crowns,) the Mitch Mason Maelstrom also shows great attention to detail, a hallmark of the Mitch Mason brand. It is the little touches like the nicely balanced date window at 6 o'clock that is conveniently lumed, the fully drilled lugs for convenient strap changes, and no less than ten layers of anti-reflective coating under the scratch resistant double-domed sapphire crystal, which helps set this watch apart from the competition.

Clearly this is a watch designed for discerning microbrand watch collectors. The attention to detail is carried through on the solid H-link bracelet as well, which features a lovely taper from 20mm to 16mm, solid end links with easy to use double quick release pins, screwed pins that make resizing a breeze, and a milled diver's safety clasp with double pushers and no less than six micro-adjusts. The polished highlights on the side of the case nicely contrast with the overall brushed finish and are attractively matched by a beveled edge on the bracelet with a mirror polished finish. A very comfortable fit is ensured due to the recessed female end links, curvature on the lugs, strong taper, and wide choice of micro-adjustment positions.

Rounding out the picture is the high beat ultra reliable Miyota 9015 automatic movement, with a smoother second hand sweep and 42 hours of power reserve.
