Alpina Seastrong Diver Extreme Automatic GMT Watch with White Dial.
Seastrong gathers the dive watches of Alpina, built for use at depths of up to 300 metres and read through luminescent hands and diving bezels. The Diver Extreme GMT adds a second time zone to that case, 40.5 mm long under a bidirectional 24-hour ceramic bezel. The case measures 39 mm in stainless steel, 12.65 mm deep.
The AL-560 winds itself from the motion of the wrist and runs 50 hours. The GMT hand turns once in 24 hours for a second time zone and carries a red triangle filled with lume, and the bezel sets a third zone against it.
With the bezel turned, 3 time zones read off a single dial. The white dial is framed by the black ceramic bezel.
Diving. Seastrong brings together the dive watches of Alpina, made for use at depths of up to 300 metres, with legible dials and solid construction. Gottlieb Hauser founded the house in 1883, and Alpina produces and assembles its movements and watches at its manufacture in Plan-les-Ouates, Geneva.
Set the GMT hand to your home time on the 24-hour scale, then move the main hour hand in 1-hour jumps to local time. For a third time zone, turn the bezel until the hour of that zone sits under the GMT hand.
About 50 hours from a full wind. Daily wear keeps the mainspring topped up, and after longer in a drawer a few turns of the crown restart it.
Alpina builds the AL-560 on a Swiss Sellita SW330 automatic base, and the house assembles its watches at its manufacture in Plan-les-Ouates, Geneva, as part of the Frederique Constant group.
The pigment on the hands and markers stores light and gives it back in the dark. It is brightest just after exposure to daylight, fades gradually through the night and recharges the next time it sees light.
