What is the Stanford University Edition?
It is a Stanford-themed version of Breitling’s Endurance Pro 44, part of the brand’s Professional collection. Breitling identifies the US-market reference as X823109C1B1S1 and describes the edition as country-exclusive in its US collection listing. Its Cardinal Red and White details mark the university, and the Stanford seal is engraved on the caseback. The watch is fitted with a black rubber strap. Breitling’s US product page lists the edition as limited to 150 pieces; it does not say how many remain available.
Price and availability
Breitling currently lists the watch for US$3,900, excluding sales tax. This is the price shown on its US storefront, not a guaranteed permanent price or a statement of pricing in other countries. The product page also lists free shipping and free returns for US online purchases; check the live listing for current terms.
The 150-piece limit is the stated edition size, not an inventory count. Breitling’s collection page identifies this reference as country-exclusive, but neither cited page establishes remaining stock or availability through other retailers. Breitling’s US Professional collection lists the Stanford reference.

Breitling characterizes the movement as ten times more accurate than conventional quartz in its April 18, 2023 University Editions announcement. That is a brand claim about the collection generally, not an independent accuracy test or a Stanford-specific measurement. The same release covers other university editions and does not establish when this Stanford model was introduced: Breitling’s University Editions announcement.
What Breitlight means here
Breitling describes Breitlight as 3.3 times lighter than titanium and 5.8 times lighter than stainless steel. Those comparisons are the manufacturer’s claims; the product information cited here does not provide an independent test or explain the measurement method. The listed case material is Breitlight, but the figures alone do not establish how the watch will feel in daily wear.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When was the Stanford edition released?
Breitling’s cited Stanford product and collection pages do not state an announcement or launch date, so a release year cannot be confirmed from those sources. The brand’s April 18, 2023 press release announced university editions for Princeton, the United States Naval Academy, the University of Alabama and the University of Michigan; it did not name Stanford. That announcement should not be treated as the Stanford edition’s launch notice.
