SKU Code: RE25J/54BL

This watch is based on a 1950s/1960s pattern exploration and adventurer watch. It features a box sapphire crystal that closely resembles the original plexiglass crystal. The movement is a Ronda R 150 or equivalent, a sophisticated 25-jewel automatic movement with an impressive frequency of 28,800 vibrations per hour (4Hz). This precision-crafted mechanism boasts a substantial 38-hour power reserve, ensuring enduring performance. Notably, it is equipped with hacking and hand-winding capabilities, exemplifying both efficiency and convenience.

The watch uses Luminova instead of the Tritium that was used in the 1960s. The main advantage of Luminova is that, unlike Tritium, it does not deteriorate with age and is non-radioactive. This variant features paint that mimics the appearance of aged Tritium paint.

The watch measures 39mm in diameter and comes fitted with a matching steel bracelet, designed to visually resemble the type of bracelets used in the 1960s. It also works well with a wide variety of NATO straps, as seen in images shared by a serving air force officer who owns one of these watches.

• Benefits of Sapphire Crystal: Many people ask about the advantages of sapphire crystal over the original plexiglass. Synthetic sapphire is by far the best material for watch crystals due to its strength, shatter-resistance, and scratch-resistance. These characteristics make it highly appealing to military and security personnel, police officers, and people who lead active outdoor lifestyles—groups that account for over 70% of our customers.

The original plexiglass crystals, made of plastic/acrylic, used in the 1960s had the drawback of being easily scratched and susceptible to cracking upon impact. Additionally, they greatly limited the water resistance of the watch. Over 90% of cracked crystal incidents involve watches with mineral glass or plexiglass. Even hardened mineral crystals do not match sapphire's durability under adverse conditions.

Sapphire crystals are strong because they are heat-treated to remove internal stresses, which can cause weakness. The crystals are then made into watch faces and coated with two layers of anti-reflective material. Interestingly, sapphire crystal is now used on the latest iPhones. While sapphire crystal comes at a higher price, it is typically found in higher-end watches due to its superior durability.
