B Navitimer B01 Chronograph – Ref# AB0138241C1A1

The B Navitimer B01 Chronograph Ref# AB0138241C1A1 is a modern reinterpretation of one of aviation’s most iconic timepieces. Featuring a 43mm stainless steel case, a deep blue dial, and the signature circular slide rule, this watch perfectly balances heritage design with contemporary craftsmanship. Originally created for pilots in 1952, the Navitimer continues to embody precision, functionality, and timeless style, now enhanced with refined finishes and the in-house B 01 calibre movement.

Its striking blue dial showcases polished baton indexes and three chronograph subdials, while the AOPA wings at 12 o’clock honor its aviation legacy. The bidirectional bezel with integrated slide rule maintains its original navigational function, making it as practical in-flight as it is sophisticated on the wrist.

Powered by the in-house B 01 automatic chronograph, this timepiece offers a 70-hour power reserve, high-frequency precision (28,800 vph), and COSC-certified reliability. Polished and brushed stainless steel surfaces create an elegant, tool-ready aesthetic, complemented by a matching stainless steel bracelet with a secure folding clasp.
