Stainless steel ( with yellow metal rider tabs to bezel ) quartz Breitling chronograph strap watch model B53011. This smart, reasonably sized watch with blue / gold dial and NEW blue strap from Breitling is often described as the SIRIUS model, though it is now no longer manufactured and we have been unable to confirm that this was its official model name. Comes with a Breitling box and our own warranty card. Only some slight wear to the bezel gives away its age and otherwise it is a great looking Breitling stopwatch. Please ask for our Breitling veterans Phil Ellison or Paul Aspinall who can demonstrate this watch to you.
