Bremont Supermarine S501 43mm Watch S501-BK-R-S

The Bremont Supermarine S501 43mm (Ref. S501-BK-R-S) honours the legendary British aircraft manufacturer responsible for the Supermarine Spitfire through robust diving watch construction that reflects Bremont’s aviation heritage. Introduced in 2009 as Bremont’s first diving watch, this demonstrates the brand’s commitment to creating practical professional diving instruments with distinctive Trip-Tick® case architecture and genuine chronometer certification.

At 43mm with 16mm thickness, this provides substantial diving watch presence whilst the patented Trip-Tick® construction offers exceptional shock resistance through three-piece architecture that protects the movement during demanding underwater operations. The DLC-treated case barrel provides superior scratch resistance whilst the inner soft iron Faraday cage protects against magnetic interference common in modern diving environments.

The modified Calibre BE-36AE delivers chronometer certification with 38-hour power reserve and Bremont’s distinctive skeletonised rotor design. The Anachron balance spring and Nivaflex mainspring provide enhanced reliability whilst the 25-jewel construction with Glucydur balance ensures long-term accuracy essential for professional diving applications.

The sapphire unidirectional rotating bezel with Super-LumiNova coating provides precise dive timing whilst the metal dial with applied indexes ensures optimal legibility. The impressive 500m water resistance validates serious professional diving capability rather than recreational swimming protection.

This Supermarine S501 suits buyers seeking authentic British aviation heritage combined with professional diving functionality. The Trip-Tick® construction and chronometer certification demonstrate genuine tool watch credentials whilst the Supermarine naming honours iconic British aerospace achievement, making this ideal for those who appreciate aviation history in serious diving watch form.
