55-hour power reserve
1/10th of a second indicator at 6 o’clock
Skeletonized bridges inspired by Zenith’s four-pointed star
The black open dial highlights the brand’s iconic star motif, while 100m water resistance ensures everyday versatility.

Steel bracelet with fold clasp
Extra black patterned rubber strap
Box, papers, and hangtag
