Bracelet and strap options—and the documented prices
Tudor’s 2020 sheet lists three configurations: a riveted steel bracelet, a blue soft-touch strap and a blue fabric strap. The document gives two Swiss prices including VAT but does not clearly attach each figure to a specific configuration in the information available here, so the prices should not be assigned to a particular strap or bracelet.
| Configuration listed by Tudor | Swiss price including VAT in Tudor’s 2020 document |
|---|---|
| Riveted steel bracelet | CHF 3,200 or CHF 3,500; the document’s available configuration detail does not establish which price applies |
| Blue soft-touch strap | CHF 3,200 or CHF 3,500; the document’s available configuration detail does not establish which price applies |
| Blue fabric strap | CHF 3,200 or CHF 3,500; the document’s available configuration detail does not establish which price applies |
These are historical Swiss prices from 2020, not current prices and not a basis for estimating the cost in another country. For a purchase, check the exact 79030B reference, local authorized-retailer price, condition (new or pre-owned) and which bracelet or strap is included.

Is the 39 mm Tudor Black Bay 58 Navy Blue a good fit?
The published 39 mm case diameter gives a useful starting point if you are comparing watch sizes, but diameter alone cannot determine how a watch will fit your wrist. The available product specifications do not establish lug-to-lug length, thickness or firsthand comfort, so try the exact configuration on if fit is decisive. Its stated 200 m water resistance and screw-down crown are specifications, not a substitute for checking the watch’s condition and service history when buying pre-owned.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Is the 79030B still available, and what is its current price?
Tudor’s current Black Bay 58 catalog page describes newer references and their configurations; it does not confirm current availability or pricing for the older 79030B. Do not assume that options shown for a newer model—including its bracelet or movement details—also apply to this reference. Check with an authorized retailer in your country to establish whether 79030B is available new and at what price. For a pre-owned watch, verify the reference and the included configuration with the seller.

What to check before buying
- Confirm that the watch is reference 79030B, rather than a newer Black Bay 58 reference.
- Verify whether the listing includes the riveted steel bracelet, blue soft-touch strap or blue fabric strap.
- Compare a current price in your market, and distinguish new from pre-owned condition.
- For a pre-owned example, ask about service history and have the watch’s condition assessed by a qualified watch professional.
