Tudor Black Bay 58 M79030N
Specs, Market Price & Buying Guide
- The Tudor Black Bay 58 ref. M79030N shrinks the Black Bay formula to 39mm with gilt accents, an aluminum bezel and the in-house MT5402 with 70 hours of reserve.
- Retail is about $3,800 on bracelet; real-world prices run roughly $3,100-3,800 — discounts are available, unlike at Rolex.
- Weak points: the aluminum bezel fades and scratches by design, no on-the-fly clasp adjustment, and a faux-rivet bracelet some find costume-y.

The Black Bay formula: snowflake hands, big crown, no date — 1958 proportions.

How it wears, by wrist size
Very good — the 39mm case and short lugs suit small wrists well.
Ideal; this is the wrist the BB58 was sized for.
Wears compact but intentional; try before assuming too small.
Reads vintage-small — the 41mm Black Bay is the alternative.
Buy or skip?
5/5 — the best-wearing vintage-style diver on sale
The BB58 nailed the brief: genuine 1950s dive-watch proportions with a modern in-house movement, at a price where ownership costs stay sane. It gives up the Submariner's ceramic bezel and brand gravity, but gains wearability the 41mm divers can't match. If you have a sub-7-inch wrist and want one diver, start here.
- You want a bezel that stays mint — the aluminum insert will age (many love that).
- You need clasp micro-adjustment on the fly — Tudor still doesn't offer it here.
- Resale outperformance matters — a Submariner is the financial answer.

Ownership costs
| Cost item | Detail |
|---|---|
| Service | Tudor suggests 5-7 year checks; service typically $400-600 via Rolex/Tudor service centers. |
| Bracelet | Faux rivets are cosmetic; the clasp is solid but lacks micro-adjust — the 2023+ 'T-fit' models fix this on other references. |
| Common issues | Aluminum bezel scratches — expected and part of the aesthetic; date-free dial keeps setting simple. |
| Warranty | 5-year Tudor warranty from card date. |
Frequently asked questions
Black Bay 58 vs Black Bay 41 — which should I buy?
Wrist size decides. Under 7 inches the 58's 39mm case is objectively better proportioned; over 7 the 41 fills better. The 58 also gets the gilt accents and aluminum bezel — the more vintage of the two.
Is the Black Bay 58 a good investment?
By Tudor standards, yes — it has held near retail for years. But no mass-market watch is an investment; buy it because the fit and style are right.
Does the BB58 bezel fade?
The anodized aluminum insert will scratch and can fade over years — deliberately echoing vintage Subs. If you want permanent mint, buy ceramic (Pelagos 39 or Submariner).
Can you wear a BB58 with a suit?
Yes — 39mm and 11.9mm thick slides under cuffs, and the gilt dial dresses up better than most divers.
