TUDOR Black Bay 58 Bronze M79012M-0001: Specs and Listing Wording

For a resale listing, collection spreadsheet or insurance record, the cleanest way to identify this watch is by its reference number: TUDOR Ref. M79012M-0001. Retailer listings describe it as either Black Bay 58 Bronze or Black Bay Fifty-Eight Bronze, and use wording such as Boutique Edition or Boutique Exclusive for this model.

The safest model name to use

The same watch appears with slightly different naming across retailer pages. Mayors lists it as Tudor Exclusive Boutique Edition Black Bay Fifty-Eight Bronze M79012M-0001; The 1916 Company uses Black Bay 58 Bronze Boutique Edition M79012M-0001; Tourneau lists TUDOR Black Bay Fifty-Eight Bronze - Boutique Exclusive (M79012M-0001).

For most listing or cataloguing purposes, these are safe, conservative formats:

• TUDOR Black Bay Fifty-Eight Bronze, Ref. M79012M-0001
• TUDOR Black Bay 58 Bronze Boutique Edition, Ref. M79012M-0001
• TUDOR Black Bay Fifty-Eight Bronze, 39 mm Bronze Case, Brown Dial

One important wording note: the retailer records reviewed here support Boutique Edition and Boutique Exclusive terminology, but they do not establish a stronger limited edition claim. If you want to use language such as limited, numbered or special edition, confirm it against the warranty card, invoice or official brand paperwork for the specific watch.

Why the bronze case needs extra description

A standard steel watch can often be described with broad condition terms such as light wear or desk-diving marks. Bronze needs a little more care. Watch Palace describes this model as having a 39 mm satin-brushed bronze case whose colour evolves to match its user’s habits.

That means a good listing should separate natural bronze ageing from actual damage. Include, where relevant:

• The current level of patina or oxidation
• Any uneven colour change, spots or visible darkening
• Scratches, dents or knocks on the case, bezel and bracelet
• Whether the watch has been cleaned, polished or otherwise treated
• Whether photos were taken in natural light, because bronze tone can shift noticeably in images

This helps buyers understand whether they are looking at normal material character or a condition issue.

Pre-listing checklist

Before publishing a listing for a TUDOR Black Bay 58 Bronze M79012M-0001, check these points:

1. Reference number: make sure the title, description, warranty card and invoice all align with M79012M-0001.
2. Model name: Black Bay Fifty-Eight Bronze and Black Bay 58 Bronze are both defensible; match Boutique Edition or Boutique Exclusive wording to your paperwork where possible.
3. Core specs: include 39 mm, bronze case, brown dial, sapphire crystal, MT5400, 200 m water resistance and unidirectional rotating bezel.
4. Bronze condition: describe patina, oxidation and colour variation separately from scratches, dents and case damage.
5. Accessories: list box, warranty card, invoice, manual, bracelet, links and any additional straps individually rather than using a vague phrase such as full set.
