Alpina is Sponsor of the Bikini Expedition Team

The Alpina Extreme Regulator, Alpina Extreme Automatic and, more recently, the Alpina Manufacture Regulator were collections designed to explore the summits. The Alpina brand is now branching out into the world of diving watches.

With its angular and sophisticated design, the newly-released Alpina Extreme Diver 1000 Meters takes over where its big sisters left off. What's more, it is decked out with a unidirectional rotating bezel displaying the time in minutes. The bezel measures elapsed time in minutes for the first fifteen minutes and then in ten minute segments after that. The luminous triangle marker highlights the 12 o'clock position.

The black watch dial displays the date within a half-moon shaped display positioned at 3 o'clock. The day of the week is also displayed within the brand's famous red triangle. Alpina has kept this red triangle as a form of decoration in the centre of the watch face.
In the classic extreme design, measuring 48 mm, the Alpina Extreme Diver 1000 Meters stands out at the bottom of the sea. Even in the darkness of the ocean-depths, the time will be clearly visible thanks to the watch hands, Arabic numerals and luminous index markers.

The brand's latest release replaces mechanical dial movement with automatic winding AL-525, a feature already used in the Alpina Extreme Automatic. This watch has a 42-hour power reserve, a blue-stained face decorated with mother of pearl and can be viewed through a sapphire glass window.
The helium escape valve located on the edge at the 10 o'clock position is an essential feature of a diving watch. In fact, when diving tens of meters below sea level for long periods of time, helium atoms can build up in the case. These atoms could expand and damage the watch when ascending. This escape valve, which is used during the decompression stop, allows the Alpina Extreme Diver 1000 Meters mechanism to remain intact.

The Alpina Extreme Diver 1000 Meters is available in two versions; one is made of surgical grade stainless steel with a black dial and the other is "Full Black", i.e. has a PVD case and a black dial.
