The Strela COSMOS CO40LAB Mechanical Chronograph

The CO40LAB chronograph is a testament to fine mechanical watchmaking. The watch design is inspired by the iconic Strela 3017 pioneer watch models that were used in space missions. The sides are brushed while the lugs and bezel are polished.

Dial Design & Features

The black dial of the Cosmos CO40CYB model echoes the aesthetics of vintage Strela watches. The black Latin Cosmos Strela dial mimics the slightly grainy, oily, and uneven texture typical of vintage Strela models. It features applied silver and green luminous baton indexes, luminous paddle hands using Superluminova, a tachymeter scale, and a telemeter scale. This design is a testament to Strela’s dedication to preserving its heritage.
