The Alpina Startimer Pilot Automatic watch is a masterclass in Swiss horology, balancing tradition with functionality. The round case is crafted from 316L stainless steel - strong yet lightweight - and finished with a matte black PVD coating that gives it a decisively modern, dynamic edge. This timepiece measures 40 mm in diameter and 11.5 mm in thickness, striking the perfect balance between a subtle and assertive wrist presence. The screw-down case back, water-resistant to 10 ATM, reflects the meticulous engineering built to handle everyday demands. Fitted with an anti-reflective treated, domed sapphire crystal, the watch ensures clear, unobstructed time reading in any conditions while effectively protecting the dial from shocks and scratches.
The dial stands out with its matte finish, eliminating glare for optimal legibility at all times. Arabic numerals, paired with luminescent indices and a minute track, deliver unmatched clarity in time display. The well-positioned date window blends seamlessly into the overall aesthetic while adding a practical, appreciated function. The brilliance of the hands, enhanced by their luminescent coating, ensures easy time reading even in complete darkness.
The heartbeat of this timepiece, Alpina's AL-525 automatic movement, embodies the precision and tradition of Swiss fine watchmaking. Operating at a frequency of 28,800 vph, it delivers outstanding reliability. Powered by a rotor, this movement strikes the perfect balance between power and subtlety, requiring minimal manual intervention thanks to its 68-hour power reserve. This caliber displays hours, minutes, seconds, and the date, making it the ideal everyday companion for those who demand mechanical excellence.
The strap of this watch is crafted in black cowhide leather, bringing a touch of sophistication and unmatched comfort to the wearer. The contrast stitching adds a refined aesthetic detail that reinforces the classic, timeless character of the piece. The pin buckle closure is both practical and secure, allowing for quick and easy adjustment. This combination of material and fastening delivers the durability and elegance that define Alpina watches, built for discerning wearers who demand versatile style.
With 10 ATM water resistance, this watch can be worn without worry in daily life and during water activities. This level of protection delivers complete peace of mind against splashes, rain, or the occasional swim.
