The Tudor Heritage Black Bay 36 ref. 79500 is a 36 mm automatic steel watch with a black dial and smooth bezel. Tudor’s archival specification lists a calibre 2824 movement, approximately 38 hours of power reserve and 150 m water resistance. Its CHF 2,400 starting price is historical, not a current retail quote; recent pre-owned asking prices are a separate and limited snapshot.
What is the Tudor Black Bay 36 ref. 79500?
Introduced at Baselworld 2016, the 79500 brought the Black Bay design into a smaller, simpler format, according to Monochrome Watches’ contemporary review. It is the Heritage Black Bay 36—not the later Black Bay 36 references 79600, M79640 or related variants. Those distinctions matter when checking specifications or comparing prices.
The archival Tudor product sheet is the source for the 79500 specifications below. It describes a steel case with polished and satin finishes, a polished smooth steel bezel and a black dial. The result is a straightforward three-hand-style Black Bay configuration without the model family’s signature rotating dive bezel.

These are manufacturer specifications, not measurements of a particular used watch. The 150 m rating does not establish the water resistance of an aged example today; condition and maintenance matter. Tudor’s archival sheet does not identify the 2824 as a manufacture movement or state that it is COSC-certified, so those descriptions should not be applied to this reference on the basis of that sheet.

How much does a Tudor 79500 cost?
Historical official price
Tudor’s archival 79500 product sheet gives a starting Swiss price of CHF 2,400 including VAT. That is useful historical context, not a current Tudor retail price or a direct conversion into today’s prices in another country.

Tudor’s later Black Bay 31/36/39/41 specification sheet lists references including 79600, 79640, 79660 and 79680, and gives the 36 mm size the MT5400, COSC certification, approximately 70-hour reserve and 100 m water resistance. This further distinguishes that later specification set from ref. 79500. The dollar price above is a US suggested retail figure for M79640-0001 only; Tudor notes that suggested prices may change.

What to check before buying a used 79500
- Confirm the reference. Make sure the listing is for 79500 rather than a later 36 mm Black Bay reference.
- Assess condition and service records. Tudor’s original water-resistance rating is not a current test result for an individual used watch.
- Check configuration and completeness. Verify which bracelet or strap is fitted and whether any additional strap, box and papers are actually included.
- Evaluate the seller and terms. Ask what authenticity checks, returns and warranty or service arrangements apply to that specific listing.
- Do not assume strap compatibility. The available specifications do not establish the 79500’s lug width or the end-fit compatibility of replacement straps; verify fit for the exact watch before ordering.
