Small wrists have long been an afterthought in the dive watch world. Not here. The Marathon 36mm OSAR-D, reference WW194026SS-2002, is a Swiss automatic diver built specifically so that wearers with slimmer wrists get the same mission-ready Search and Rescue watch as everyone else, here in black on a stainless steel bracelet.

The numbers tell the story. A 36mm diameter, 13mm thickness and a compact 43.5mm lug-to-lug span mean the case sits inside the edges of a smaller wrist rather than overhanging it, and the 18mm lugs let the bracelet taper naturally. The proportions keep the watch balanced, so it does not flop to one side or catch on cuffs. Yet nothing essential was trimmed away: you still get a sapphire crystal, a guarded screw-down crown, 300 meters of water resistance and Marathon's oversized, glove-friendly 120-click bezel.

The OSAR-D's dial is designed for quick reading at any size. Large geometric indices and broad hands are filled with MaraGlo, Marathon's light-charged luminous material, and a cyclops lens magnifies the date at 3 o'clock so it remains easy to see on a smaller dial. A Sellita SW200-1 automatic movement keeps it running with every move you make.
