This watch is based on a 1950s/1960s military design. It features a box sapphire crystal that closely resembles the original plexiglass. The movement is a sophisticated Ronda R 150 or equivalent, boasting 25 jewels and a frequency of 28,800 vibrations per hour (4Hz). This high-precision mechanism offers a substantial 38-hour power reserve, ensuring reliable performance. Equipped with hacking and hand-winding capabilities, it exemplifies both efficiency and convenience.

Instead of the Tritium used in the 1960s, this watch employs Luminova. The main advantage of Luminova is that it does not deteriorate with age and is non-radioactive. The paint color mimics aged Tritium paint, and although the "T" is encircled (indicating Tritium), this is included purely for historical accuracy.

This watch measures 39mm in diameter and comes with two NATO straps: one black and one standard British issue Admiralty gray.

Benefits of Sapphire Crystal: Many people ask about the advantages of sapphire crystal over the original plexiglass. Synthetic sapphire is the superior material for watch crystals due to its exceptional strength and resistance to shattering and scratching. These qualities make it highly appealing to military and security personnel, police officers, and individuals with active outdoor lifestyles—groups that make up over 70% of our customers.

The original plexiglass crystals, made from plastic/acrylic materials used in the 1960s, were prone to scratches and cracks, and they limited the watch’s water resistance. Over 90% of cracked crystal incidents involve watches with mineral glass or plexiglass. Even hardened mineral crystals do not match sapphire's durability under harsh conditions.

Sapphire crystals are heat-treated to eliminate internal stresses, enhancing their strength. They are then coated with two layers of anti-reflective material. Interestingly, sapphire crystal is now also used in the latest iPhones. Despite its higher cost, sapphire crystal's superior quality justifies its use in higher-end watches.
