Breitling Top Time B01 Racing

Breitling Top Time B01 Racing AB01771A1L1X1 has a 38 mm steel case, the sort of size the original 1960s racing chronographs wore. The case measures 13.07 mm thick and carries an 18 mm lug width, with a cambered sapphire crystal glareproofed on both sides. Inside is the self-winding B01 calibre, a chronometer-certified movement with 70 hours of power reserve. As a chronograph it has a small seconds display and a tachymeter scale on the dial, useful for reading speed over a measured distance. This is a limited edition, finished with a green dial and paired with a green calfskin leather strap on a steel tang-type buckle. The non screw-locked crown still allows the case to hold its rating of 100 metres.
