Le Grand Plongeur, French for "the big diver," is the other name for Marathon's JSAR, and it fits. The Marathon JSAR WW194018SS-0107 is a 46mm Swiss quartz dive watch on a stainless steel bracelet with a black dial, made for those who want their tool watch to have real wrist presence.

The JSAR has deep Canadian roots; it was developed for provincial police services throughout Canada. In practical terms, the larger case provides a broad dial, a chunky, easy-to-grip unidirectional bezel and a sturdy screw-down crown protected by guards. At 46mm wide, about 17.5mm thick and 55mm lug to lug, it is unapologetically big, and it looks proportionate on larger wrists where a 40mm watch might seem undersized.

On the steel bracelet, all that steel feels purposeful rather than heavy-handed. The 22mm bracelet matches the case's scale, and the brushed finish keeps the look matte and businesslike. Swiss ETA F07.115 HeavyDrive quartz provides accurate, high-torque timekeeping and an end-of-life battery warning, while MaraGlo lume keeps the black dial readable after dark.
