The Air Commando D45-SL by Xezo is where form meets function. This watch?s large face, 2-layer guilloche dial, bezel features, and solid stainless steel (316L) case, and genuine black calf-skin leather band construction are built to strict standards, all the while it maintains a classic vintage look. This line was inspired by the 60th anniversary of the famous air commando group, and now the 4th edition is available with an updated case, band design and most importantly, updated Swiss-made movements. Each design is produced in limited 500-piece series. The two bezels operate independently, each offering an additional layer of complexity to this fine piece. Designed to track elapsed time in minutes or seconds the outer bezel features raised, diamond-cut numerals in dark blue finish. Their deep blue and polished finish is sure to attract attention. The inner bezel, operated by the 10 o’clock crown, records elapsed time in hours or functions as a secondary time zone. On the face, the beautiful silver guilloche design with blue accented Roman numerals and hour markers, makes a bold statement. Each of the hour markers, and the hands are illuminated clearly with Swiss Super-Luminova® overlays. Surprisingly accurate, ( 20/-10 seconds/month) this shock-proof water-resistant (200 M) timepiece holds a long lasting battery. Specifications include 3 mm thick Swiss sapphire crystal glass, with an inner anti-reflective coating, 54x45x13mm case (not including crown), 230x21x4mm band.
