When you think of Breitling, chronographs and pilot's instruments come to mind first. The Lady Premier breaks from that mould entirely: a 36 mm case with no tachymeter, its dial making its case through colour alone. Reference A10310121Q1P1 carries dial code 21Q, catalogued internally as "Aubergine Sunbeam" — a warm violet with a sunray finish that shifts between Bordeaux and plum. Collectors commonly call it the "Purple Lady Premier", though aubergine describes the hue far more precisely.
## Calibre B10 and What It Means for Daily Wear
The case measures 36 millimetres across — well-proportioned on a wrist under 16 cm, it reads as more delicate on larger ones. Power comes from Calibre B10, a quartz movement on an ETA base. Quartz at this price point is not a compromise but the more pragmatic choice: lower maintenance than an automatic and more accurate over months of continuous wear. In a case this size, a full rotor movement would also be harder to accommodate without raising the profile.
## What Bezel Code 121 Means When You're Buying
"121" in the reference string stands for "Fixed Smooth Steel" — a plain, unmarked steel bezel with no stones. That makes it the more understated alternative to the diamond variant with code 671 that Breitling offers within the same reference family. For buyers drawn primarily to the aubergine shade, the steel bezel provides a cleaner frame: the dial colour takes centre stage with nothing to compete against it. On the secondary market the diamond version commands higher prices, but appeals to a narrower pool of buyers.
Brand profile: Breitling
Breitling is known for aviation and dive watches. Chronographs (Navitimer, Chronomat) are the most frequently counterfeited. Pay close attention to slide rule details and COSC certification.
- Wing logo: a genuine Breitling logo shows the anchor and wing tips that NEVER touch — precise negative space between them — fakes let the tips meet or overlap
- 3D 'B' crown: the 'B' on the crown must appear three-dimensional with a light reflection on the curve — a flat 'B' = fake
- Bezel scale vs. dial: the outer white bezel scale must align precisely with the inner black dial indices — fakes show misalignment
- Date disc depth: a genuine Navitimer date disc sits flush with the dial plane — fakes show the date window as a 'crater' (noticeably sunken or raised)
Serial number format: Breitling serial numbers: alphanumeric, located between the lugs at 6 o'clock. Format: one letter + 8 digits (e.g. 'AB012012'). Older models: digits only.
