Sleek, dark and full of surprises, the Tissot PRX Digital 40mm in black is the PRX for people who like their watches with a little science-fiction edge. At first glance it looks like a black-dial steel PRX; touch a pusher and a digital display emerges from beneath the glossy mirror dial.

Tissot created the PRX Digital as a tribute to the late-1970s fusion of style and electronics, when the PRX itself was born. This model delivers an impressive feature set for its size: time with seconds, day and date, a second time zone, a chronograph and an alarm. The black mirror dial offers a moody, high-contrast look that works beautifully with the brushed and polished steel case.

At 40mm and about 10.9mm thick, it has a sporty presence while staying slim. With sapphire crystal and 100-meter water resistance, it is ready for daily life, travel and the gym alike.
