The Praesidus DD-45 "OG" is based on one of the longest-running field watch designs ever.

During World War II, the British War Office commissioned a group of watches—later known as the "Dirty Dozen"—to provide soldiers with clear and reliable timekeeping in the field. Their design set the standard for the modern military field watch: simple, highly legible, and built for reliability under pressure.

The Praesidus DD-45 retains this functional design, updating it for modern use. The push-button crown and 10 ATM water resistance enhance protection in humid environments, along with the flat sapphire crystal.

Inside, the watch is powered by a high-precision, American-made quartz movement. Chosen for its precision, reliability, and minimal maintenance, it ensures consistent timekeeping without the need for manual winding, making it a practical instrument for everyday use.

Each DD-45 is assembled in the United States, combining one of the most recognizable military field watch designs ever produced with modern materials and dependable performance.
