The Alpiner Extreme Automatic is a rugged sports watch measuring 41 x 42.5 mm. At the heart of its design, a sturdy rounded-square case with a brushed finish features a black dial, a date window at 3 o'clock and a see-through caseback. The integrated black textured rubber strap (with no seam against the case) offers comfort, durability and a modern feel. The rubber grip crown makes it easy to operate bare-handed or with gloves. Water resistant to 200 m.
