The Vostok-Europe Expedition North Pole Polar Legend – Pulsometer Automatic Watch (YN55-597C731B) stands as a paragon of durability and precision, engineered for those who venture into the world's most extreme environments. This watch is an integral part of the "Expedition North Pole" collection, designed not merely as a fashionable accessory but as a crucial survival tool for the unforgiving conditions of the North Pole. Its striking color palette ensures visibility against the severe, white expanse of the Arctic.

This robust timepiece features a large 47mm case crafted from 316L stainless steel, which offers exceptional impact resistance and corrosion protection. The case combines a matte and brushed finish that encapsulates its rugged yet refined aesthetic. It is fortified with a 4.0 mm thick K1 crystal, renowned for its scratch resistance and designed to withstand pressures up to 20 BAR (200 meters/660 feet), making it suitable for both underwater adventures and extreme terrestrial conditions.

The dial is intricately designed with multiple layers, featuring luminescent indexes and skeletonized hands that ensure legibility in all lighting conditions—from the blinding sunlight to the dark polar nights. A luminescent two-ended second hand further guarantees that time can be read effortlessly at any moment.

One of the most distinctive features of this model is its bi-directional rotating bezel, which incorporates both a Pulsometric scale and a Respiratory scale. This allows wearers to manually monitor their pulse and breathing rates, crucial health metrics that can be life-saving in remote areas where electronic devices are unreliable. This function underscores the watch’s role not only as a timekeeper but also as a vital health monitoring instrument.

The watch is versatile in terms of wearability, coming equipped with two strap options: a tough silicone strap and an elegant leather strap. Both straps feature quick-release spring bars, enabling easy and quick customization without the need for tools, suitable for adapting to different activities or comfort needs.

Driving the functionalities of this watch is the YN55 automatic movement from Seiko Epson, noted for its steadfast reliability and accuracy. Additional features include a calendar with quick date correction and a stop-seconds device, which aids in precise time-setting.

Altogether, the Vostok-Europe Expedition North Pole Polar Legend – Pulsometer Automatic Watch merges practicality, resilience, and aesthetics, making it an essential tool for polar explorers and outdoor enthusiasts who demand the most from their gear.
