The DD-45 “Tropical” is the result of two years of development with a dial supplier. This watch features a deep brown dial and patina indexes and hands, designed to mimic a rare aging process. Over the years, exposure to sun and humidity causes black dial paint to transform into a dark brown. This unique “tropicalization” effect on the DD-45 creates a distinct and vintage look, reminiscent of some rare Dirty Dozen watches seen today, 80 years after their initial production. 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.
