Honoring the legacy of the Lunokhod-2 lunar rover, the Vostok-Europe Lunokhod 2 Grand Chrono Tritium Tube 6S30/6203211 is a timepiece that boldly encapsulates the spirit of space exploration and innovation. This watch is meticulously handmade in Lithuania, showcasing the brand's commitment to superior craftsmanship.

The Lunokhod 2 Grand Chrono features an automatic helium valve, a unique feature designed for deep-sea diving. When divers ascend after a deep dive, the helium valve allows the helium gas that infiltrated the watch during the descent to safely escape, preventing potential damage from pressure differential.

The watch is set apart by Swiss-made tritium tubes, providing exceptional and consistent luminosity. The tritium tubes are mounted in patented reflective "candle holders", enhancing their illumination for improved readability under any light condition.

Boasting an imposing 49mm diameter and 17.5mm thickness, the watch's casing is forged from durable 316L stainless steel. A black PVD plating further enhances its robust aesthetic and resilience. The screw-down crown ensures a secure seal for the watch, while the unidirectional rotating bezel allows divers to safely keep track of elapsed time.

Protection of the dial is ensured by a substantial 3.5mm thick K1 crystal, complete with an anti-reflective coating for optimum legibility in various lighting conditions. With a remarkable water resistance of up to 300m, the Lunokhod 2 Grand Chrono is well-suited for water-based adventures.

The watch comes mounted on a silicon strap, offering comfort and durability. A supplementary leather strap is also provided in the kit, allowing wearers to customize the look based on their preference. A strap changing tool ensures easy swapping between the straps.

Limited to just 3000 units, the Lunokhod 2 Grand Chrono provides an element of exclusivity. It's powered by a reliable Miyota 6S30 chronograph movement, delivering accurate timekeeping.

In summary, the Vostok-Europe Lunokhod 2 Grand Chrono Tritium Tube is a striking testament to technological marvels and human ingenuity. It's not just a watch, but a story of exploration and adventure, encased in a stylish and robust timepiece.
