Breitling Transocean A45310: A Classic Day-and-Date Watch
The Breitling Transocean A45310 is an elegant automatic watch that combines a refined, vintage-inspired design with the everyday usefulness of a day-and-date display. Part of Breitling’s Transocean collection, it offers a more formal alternative to the brand’s aviation-focused models while retaining the precision and attention to detail associated with the name.
Design and dial
The A45310 has a round stainless-steel case measuring approximately 43mm across. Its polished surfaces and clean profile give it a dressier appearance than many of Breitling’s sport watches, while the size ensures a confident presence on the wrist.
The dial is designed for clarity and balance. The day and date are shown in separate apertures, with the day display at 12 o’clock and the date at 6 o’clock. Applied hour markers and simple hands keep the time easy to read, while the restrained layout lets the calendar displays take centre stage. Dial colours and details can vary between examples.
Movement and functions
Inside the Transocean A45310 is Breitling Calibre 45, an automatic movement with day and date functions. It is a self-winding mechanical movement, so it is powered by the motion of the wearer’s wrist and can also be wound by hand. The model is associated with COSC chronometer certification, indicating that the movement has been tested for accuracy by the Swiss Official Chronometer Testing Institute.
The day-and-date complication is practical for everyday use, and the watch presents it in a way that is straightforward to read. As with any mechanical watch, accuracy and power reserve can be affected by the condition of the movement, how the watch is worn and when it was last serviced.
Comfort and everyday wear
Depending on the specific example, the A45310 may be found on a stainless-steel bracelet or a leather strap. A bracelet gives the watch a more contemporary, versatile look, while leather brings out its dress-watch character. The 43mm case is substantial, so it is worth trying the watch on if possible, particularly for those accustomed to smaller timepieces.
Water resistance is commonly specified at 100 metres, but the performance of a pre-owned watch depends on the condition of its seals and whether it has been tested recently. Water resistance is not permanent; a watch should be checked before exposure to water, especially if its service history is unknown.
Heritage of the Transocean collection
The Transocean name draws on Breitling’s history of watches made for travel and international journeys. The modern collection revisits that heritage with a cleaner, more understated design than the brand’s best-known pilot’s watches. The A45310 reflects this approach: it is recognisably a Breitling, but with a more formal and balanced appearance.
Buying a pre-owned Breitling A45310
When considering a pre-owned A45310, check that the reference and serial numbers are consistent with the watch’s documentation and case. Ask about its service history, confirm that the day and date change correctly, and look closely at the case, dial, hands and bracelet or strap. Original papers and packaging can be useful, but they do not replace a careful inspection of the watch itself.
For added confidence, consider having the watch examined by a qualified watchmaker or an authorised Breitling service centre. They can assess the movement, verify its condition and check the seals. The exact specification may vary by production period or individual example, so confirm details against the watch and its documentation before buying.

For buyers who value Breitling’s horological identity but prefer a dressier style, the A45310 is a noteworthy member of the Transocean family.
