Quick-change system
Water-resistant to 5 ATM
Washing your hands, rain, and splashes are no problem. The watch is not suitable for swimming. This specification describes the test pressure in the laboratory, not a diving depth.

Domed sapphire crystal
All Sternglas watches feature sapphire crystal with double anti-reflective coating. Sapphire is the third-hardest transparent material after diamond and moissanite.
Miyota 6P23 with date
The Miyota 6P23 quartz movement operates behind the stainless steel case back, secured with four screws.
The movement powers the date display at the 12 o’clock position and the 24-hour display at the 6 o’clock position. The accuracy is -20/+20 seconds per month, with a battery life of up to three years.
The Zirkel X thus combines precise timekeeping with two practical additional functions that blend harmoniously into the symmetrical dial design.
