The Erwin LAB03 is a watch that has it all... hardcore mechanical chops from the genius of Maria & Richard Habring underneath a masterfully hand guilloched bronze dial by real American hero J.N. Shapiro. An interesting side note is the LAB03 is the first watch to receive official Chronometer Certification from the Horological Society of New York, America’s first watchmaking guild, thus the balance cock is stamped with the HSNY Seal.

This Special Edition sold out almost instantaneously when it was released in 2022.

At the heart of the Erwin LAB03 lies the in-house Habring² A11MS manual wound caliber, which operates at 4Hz and delivers a 48 hour power reserve. This caliber features a central-mounted jumping seconds hand that advances with a precise one-second tick reminiscent of vintage observatory pieces or a traditional quartz watch. A tangential screw is in place for fine adjustment and the anti-magnetic escapement is fit with a Carl Haas hairspring of Chronometer quality.

Stainless steel case is in like new condition and measures 38.5mm x 10.3mm x 46mm lug-to-lug. Complete w/ Box and Papers, HSNY Chronometer Certification.
