At the heart of this Navitimer B01 beats a self-winding mechanical movement delivering a 70-hour power reserve, operating at 28,800 vibrations per hour with 47 jewels. The chronograph function offers 1/4-second precision with 30-minute and 12-hour counters, while index hour markers and luminescent hands ensure clear readability at a glance.
The 43mm round stainless steel case is fitted with a cambered sapphire crystal glareproofed on both sides, along with a screwed-in sapphire crystal caseback. The bidirectional rotating bezel incorporates a circular slide rule — a hallmark of the Navitimer's aviation heritage. Water resistance is rated to 30 meters.
A black alligator leather strap secured by a stainless steel fold clasp lends the piece a polished, classic character. Swiss Made and complete with its original box and papers, this Navitimer B01 Chronograph is presented in reference AB0138241C1P1 for the collector who values both technical depth and enduring style.
