On a red-eye flight or a three-day hike, the less a watch weighs, the better. Reference WW194015SG-0106, the Marathon General Purpose Quartz with Date in sage green, is a 34mm composite field watch so light you barely notice it, yet it shows the time, the date and a tritium glow whenever you look.

The secret is the fibreshell composite case, which is far lighter than steel and comfortable against the skin in any temperature. Finished in sage green, it is matched here with a sage green DefStan nylon strap that holds the watch securely without adding bulk. The black dial carries no government markings; it presents bold numerals, 12- and 24-hour scales, tritium tubes on the hands and markers and a date at 4:30, useful when days start to blur together on the road.

Timekeeping is handled by the Swiss ETA F06.115 HeavyDrive quartz, a high-torque movement with an end-of-life indicator, so there is no winding and fair warning before a battery change. The 11.5mm case is built to MIL-PRF-46374G and fitted with sapphire crystal. For travelers, hikers and anyone who values comfort, it is a natural choice.
