Premier B15 Duograph 42 Perhaps it can be foreseen that sooner or later Premier chronographs will be given a drag pointer. After all, as a chronograph expert, the watch company has something to prove in this complex field. Willy Breitling launched the first Breitling Duograph in 1944. The name Duograph, which means two chronograph hands, initially established itself in Breitling, replacing the more common term "drag pointer" or "chasing hands."
The Premier Duograph of the 21st century was born. Breitling introduced a new movement for this watch, the Breitling-made movement B15. The movement uses the internal rattrapante movement B03, but it is manually wound instead of an automatic movement. The height of the core is 8.68 mm and the total height of the case is 15.35 mm. The integrated crown button for dragging the pointer function is a special function previously used on historical models.
The new Premier B15 Duograph 42 has a glossy dark blue dial and a 42 mm stainless steel case, or a black dial and an 18 carat red gold case. Breitling's self-made manual winding movement B15 has also passed the COSC certification and can provide a power reserve of approximately 70 hours.
If you look at the 1946 Datora Reference 805, you will find that the new model is surprisingly similar to its historical counterparts. Breitling just added some brilliance to it with some new small details and the built-in self-winding movement B25.
