The DD-45 “Patina” represents the culmination of a two-year collaboration with a dial supplier. This dial showcases authentic patina indexes and hands, achieved through a process combining chemical aging and extensive UV light exposure. The outcome is a distinctively unique dial that resembles an original Dirty Dozen watch, as if it has aged naturally over 80 years. It emphasizes the genuine age and wear of the originals, reflecting the rugged use they endured in the hands of military personnel. The DD-45 is not just a visual tribute but also a modern one to the original Dirty Dozen watches, which were designed for the British War Office to standardize high-performance field watches for the British Army. The DD-45 surpasses the original specifications, bringing the design into the 21st century. Originally intended to be “Waterproof,” the DD-45 now has 10ATM water resistance and a screw-down crown, ensuring durability and safety in wet conditions. Additionally, the double-domed sapphire crystal provides best-in-class scratch resistance. Respecting the historical origins of the original Dirty Dozen watches, all twelve of which were produced in Switzerland, the DD-45 is powered by the Swiss-made Landeron L24 movement. This movement features 28,800 beats per hour (BPH) and 25 jewels, ensuring a smooth second-hand movement and high precision, ready for use in any condition.
