Fly well under the radar with a pusherless chronograph featuring Habring²'s patented Crown Operation System (COS), allowing you to start, stop, and reset the chronograph with a seamless turn of the crown.

Kudos go to the Habrings in creating a mechanism which is buttery smooth in operation yet difficult to inadvertently trigger during normal wear. This ZM version (Zentraler Minutenzähler) of the COS records elapsed minutes on the central axis by way of the red hand with arrow tip, seconds without the tip. The reverse side reveals the Habring² A08COSZM caliber which operates at 4 Hz and carries a power reserve of approximately 48 hours. A tangential screw is in place for fine adjustment and the anti-magnetic escapement is fit with a Carl Haas hairspring of Chronometer quality.

The Stainless Steel case measures 42mm x 14mm x 52mm lug-to-lug and is in excellent condition. No Box & Papers. Furnished on a DeLugs calfskin strap with pin buckle.
