In the TRI-03 Power Reserve GMT COSC, form and function can exist with elegance. The TRI-03 can track multiple timezones simultaneously, with an indicator displaying what remains of its 42-hour power reserve. In our world, accuracy is everything, and this chronometer delivers.
Simplicity in its finest Swiss form. Paying homage to the elegance of the 40s and 50s dress watches with its retro-temporary style, the TRI-01 Small Second COSC features a chronometer-certified movement inside its Swiss-made case.
