The Seals Model A is largely defined by its case which is unchanged for the A.5 at 41mm wide and 12.2mm thick with a water resistance of 100m and topped by a flat sapphire crystal with anti-reflective coating. To me, the case shape with its bezel seems to echo the logo (also echoed by the lume-filled tip of the seconds hand), which in turn is based on the hexagonal bolts on tanks, we are told. It also reminds me a little of a more angular Tutima M2 case or maybe a Dietrich Time Companion. With the thick and heavy-looking metal bracelet and folding clasp, most surfaces have a brushed finish with some welcome contrast provided by the polished edges of the tall bezel… More here.
