Housed in a 43mm stainless steel round case, the Transocean Chronograph reference AB0152121G1A1 features a silver dial with black subdials, applied polished index hour markers with luminous tips, and a date window positioned between the 4 and 5 o'clock indices. A polished stainless steel fixed bezel frames the convex sapphire crystal, which carries a glare-proof treatment on both sides, while a transparent sapphire crystal caseback allows a view of the movement within. The crown is non-screw-locked and fitted with two gaskets, and water resistance is rated to 30 metres.
Driving the watch is the Breitling Caliber B01 automatic movement, a COSC-certified chronometer housing 47 jewels and delivering a power reserve of approximately 70 hours. The chronograph and date complications complete the functionality of this professional-style timepiece.
The watch is fitted with a stainless steel mesh bracelet secured by a folding clasp. It is offered in unworn condition with the original Breitling box, Breitling papers, and booklet included, and is covered by a Breitling warranty.
