When Breitling launched the Endurance Pro 44 on August 26, 2020, the light blue version was nowhere to be found. The lineup debuted in five colors at an introductory price of SGD 4,290 in Singapore — Light Blue was not among them. That changed in 2022: the variant joined the collection, and the secondary market immediately christened it "Tiffany Blue," even though Breitling itself simply calls it "Light Blue."
## The Strap Update That Changed the Reference
In 2024, Breitling gave the strap a thorough redesign. The first-generation S1 band gave way to a new S2 design, and the X82310281B1S1 became the X82310281B1S2 — the version currently in production. At the same time, the 44mm lineup was trimmed: Yellow (A41) and Red (D91) were discontinued, while Black (E51) was added to the mix. The active range has stood at five colors ever since, with Light Blue among them. Also in 2024, Breitling introduced the smaller 38mm Endurance Pro (X83310).
## Why the Collector Market Has Three Names for the Same Watch
"Light Blue" is Breitling's own name. "Tiffany Blue" traces back to the earliest eBay listings from 2022, when the color immediately triggered the association with the iconic jewelry brand. "Baby Blue" circulates mostly in forums and on classified ad platforms. All three names refer to the same reference. Anyone searching for the X82310281B1S2 on the pre-owned market will find it listed under all three — but for market value research and authentication, the reference number remains the only reliable anchor.
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.
