A chronograph only earns its complications if you use them, and the Marathon CSAR WW194014SS-0108 makes that easy every day. This 46mm automatic Chronograph Search and Rescue watch, on a stainless steel bracelet with a black dial, is the kind of tool you'll find yourself reaching for to time a steak on the grill, a run, a meeting that's gone long or a batch of laundry.

Daily practicality is a big part of the CSAR's appeal. Start, stop and reset the chronograph with a press of the pushers; read elapsed minutes and hours from the counters; use the rotating 60-minute bezel for a second, independent timer. The day and date at 3 o'clock mean you never need to check your phone for either. Because the ETA Valjoux 7750 is self-winding, regular wear keeps it running, with roughly 48 hours of reserve when you take it off for the weekend.

The bracelet suits that everyday routine. Brushed 316L steel holds up to sweat, rain and the bumps of daily life, and it gives this substantial 46mm case the support it needs to sit evenly on the wrist. At night, tritium on the hands and markers means you can still read it without reaching for a light.
