Konstantin Chaykin SC02C
The Konstantin Chaykin SC02C is a limited edition chronograph developed in collaboration with Roscosmos, designed to withstand the rigors of spacewalks. Drawing inspiration from four actual spacewalks and years of testing on the International Space Station, this watch serves as a functional instrument for cosmonauts and a collector's piece, reflecting the brand's long-standing fascination with space exploration.
- Limited to 28 pieces
- 45-hour power reserve
- Water resistant to 10 ATM
- Withstands high vacuum down to one-millionth of normal atmospheric pressure
The SC02C includes two straps: one for everyday wear and a longer one designed to fit over a spacesuit cuff.
The watch's design evolved from a research program with Roscosmos that began in 2018, with experimental watches accompanying four spacewalks.
Unlike earlier prototypes, the SC02C features a simplified black dial with large markers, a 12-hour chronograph, and a rotating 12-hour bezel for tracking elapsed time.
The flat sapphire crystal is secured with a reverse dovetail mounting to withstand pressure differences between atmospheric pressure and vacuum.
The steel case has rounded surfaces to prevent damage to spacesuits and includes an anti-magnetic cover and secured strap pins.
Konstantin Chaykin's manufacture produces 60 components for the modified K.20-5 caliber, including parts for the 12-hour chronograph.
The production model's case size is 0.5mm smaller than the experimental watches worn in space, and its movement finishing has been improved.
Every production watch undergoes extensive laboratory testing, including centrifuge, vibration, impact, thermal cycling, solar simulation, sealing, and vacuum resistance checks.
