Breitling Superocean 46mm Watch

Q: What exact model is this Superocean 46mm?
A: It is the Breitling Superocean Heritage 46, reference A17320, produced in 2016. It features a 46 mm stainless steel case, black dial and black unidirectional bezel on the Ocean Classic steel mesh bracelet.

Q: What movement does it use and what is the power reserve?
A: It runs the automatic Breitling Calibre 17 (COSC‑certified), a robust movement based on ETA/Sellita architecture with a power reserve of approximately 38–40 hours. Actual running time can vary with wear patterns.

Q: Is this a chronograph?
A: No. This reference is a time‑and‑date dive watch without chronograph sub‑dials or stopwatch functions.

Q: How water‑resistant is it and can I dive with it?
A: Rated to 200 m / 660 ft, it is suitable for swimming, snorkelling and recreational scuba diving. Always ensure the crown is fully screwed down, avoid hot showers/saunas, and have water‑resistance tested periodically—especially on a pre‑owned piece—before any immersion.

Q: How large does the 46 mm case wear?
A: It has a substantial wrist presence. The case is about 13.6 mm thick with an approximate lug‑to‑lug of 56 mm. The mesh bracelet drapes well, which helps balance the size on the wrist.

Q: What is the lug width and can I change straps?
A: The lug width is 24 mm, so a wide range of 24 mm straps (rubber, leather, or mesh) will fit. Additional straps are not included unless stated under product information.

Q: How is the mesh bracelet sized and what wrist will this watch fit?
A: This example fits wrists up to 20 cm as supplied. The Ocean Classic mesh sizes down by removing screw‑secured links near the clasp and using the clasp’s micro‑adjustment. Because screws can be thread‑locked, we recommend sizing by a professional watchmaker to avoid damage.

Q: Is the bezel unidirectional?
A: Yes. The bezel on the Superocean Heritage 46 is unidirectional for safer timing during water activities.

Q: What servicing does a watch like this need?
A: Breitling advises a maintenance service about every 2 years (seals, water‑resistance checks, cleaning) and a complete service roughly every 4–6 years, depending on use and environment. Regular testing helps maintain water resistance.

Q: What is included with this item and how is its condition?
A: Please refer to the product information on this page for everything included. This piece is offered without additional items and is in Very Good pre‑owned condition, showing scratches on the clasp and case back with light signs of use internally.
