Alpina has developed its own solid stainless steel bracelets which are superbly comfortable, even in the hottest climate. The unique construction is extremely strong and easily adjusted.

The noiseless rotor inside an automatic watch converts your forearm's every motion into energy that winds the mainspring. When fully wound, it provides the watch with a power reserve of about 40 hours.

A number of Alpina watches feature high-quality selfwinding mechanical movements. Provided it is worn regularly and actively, the watch should never require manual winding. Should it remain off the wrist for some days, the movement can be wound manually. Wind the movement by turning the crown clockwise approximately 15 full rotations. Push the crown back in. If a screw crown, unscrew the crown by turning the crown counterclockwise. To lock a screw crown, push the crown into the case and turn clockwise until it is tightly screwed in place.

The traditional automatic watch is made up of about 130 parts assembled in the three main parts, which are the source of energy, the regulating parts and the display. The number of component parts is much higher in so-called complicated watches (date, phases of moon, retrograde hand, etc.). The "ébauche" (about 60 parts) fitted with the regulating and certain other parts, forms the movement, in other words the internal mechanism of the watch, which makes it possible to maintain a constant tension in the spring once it has been wound manually or automatically (by movements of the wrist) and to regulate the display by means of the hands (hours, minutes, seconds). A watch is said to be finished when the movement has been fitted with a dial, hands, and case.

Each watch is individually adjusted and checked on its accuracy before leaving the workshop. Please find here the table of Alpina accuracy.

Alpina fits fine quality genuine leather straps on its watches. In addition to the strap with the regular buckle, a special clip or 'deployment' clasp is available enabling options in choice to complement the watches.

The buckle and special clip are made of stainless steel and bear the Alpina logo.
