What reviewers agree on

Liked
  • Strong value: one of the cheapest mechanical GMTs from a major brand
  • Bright lume that is easy to read at night
  • Comfortable jubilee-style bracelet
Worth knowing
  • It is a "caller" GMT: the extra hand tracks a second time zone, but you can't jump the local hour hand on its own when you travel
  • Hardlex (mineral) crystal, not sapphire, so it scratches more easily

Will it fit my wrist?

Rough rule of thumb from lug-to-lug length (46 mm), not a promise. Wrist shape matters; try one on if you can.
