Four spacewalks.
The SC02C isn’t a watch that had a single orbital cameo. Konstantin Chaykin developed the chronograph in collaboration with Roscosmos and the design was tested during four extravehicular activities, specifically around the demands of working outside a spacecraft.
Purpose first
Konstantin Chaykin framed this as a watch engineered for EVA use rather than a conventional wrist chronograph adapted for space. That distinction matters: controls, durability and usability under suit conditions typically drive different decisions than those for diving or racing watches.
What we know from testing
Monochrome Watches first reported the project and the flight-testing. The headline fact is the operational validation — four spacewalks — which shifts this from a speculative concept to a field-proven instrument. The collaboration with Roscosmos gives it an official working provenance rather than a promotional tie-in.
Missing details to watch for
The announcement highlights the mission-focused development and the spacewalk tests, but the technical dossier remains incomplete in public reporting. Key specs collectors and buyers will want — caliber identity, case dimensions, materials, power reserve, water resistance and pricing or availability — have not been disclosed alongside the testing claim.
Market angle
Watches with verified spaceflight credentials trade on story and documentation as much as on metallurgy or movement finish. The SC02C’s Roscosmos-backed testing gives it a rare provenance. Still, valuation will hinge on the full spec sheet and how the design solves real EVA constraints compared with other mission-worn instruments.
Watch for the detailed technical release. The four-spacewalk test is the headline; the movement and production details will decide who actually buys one.
As Monochrome Watches first reported, this is a purpose-built, space-tested chronograph — and the next move is simple: confirm the movement and availability, then compare it directly to other flight-proven watches when the full specs arrive.
