Longines pulse chronograph speedometer

This pulse chronograph developed from the classic special function watch of the 1920s can be used for medical purposes. The reason why it can be called a medical watch is mainly because its red pulse meter scale is exquisitely displayed on the dashboard. The pulse measurement results can be known just by operating the crown. The operation is simple and the results are accurate. The 40mm diameter stainless steel case is just the right size, and the L788.2 ETA movement and 54-hour power reserve ensure high-quality operation and durability.
Longines Military Flag Series
This Longines watch inherits the design of many of the first mechanical watches. Its slender silhouette and in-place detail processing combine classical and elegant design style with pure watchmaking craftsmanship, showing a lasting military flag mechanical watch style. It is clear that the Longines watch brand has the spirit of active exploration, pragmatism and innovation. The price of this watch is 15,900 yuan. The diameter of the mechanical watch is 38.6 millimeters (mm). It adopts automatic mechanical movement and the casing is made of fine steel. It is waterproof to a depth of 30 meters and can also be worn while bathing and swimming.
Longines Concas series classic retro style 1955-2054
The most important and boldest step for the limited edition mechanical watch is to use the original 35 millimeter (mm) packaging size. You're right, 35 millimeters (mm). From today's perspective, 35 millimeters (mm) is undoubtedly the size of a women's watch, but it was exactly the size of a mechanical watch worn by men of that era. Longines insists on using a 35 millimeter (mm) instrument panel to perfectly present the original version of the 1950s era, which is very risky, but worth it!
