About the price index Fifty Fathoms Blancpain
Born in 1953, the Blancpain Fifty Fathoms is often considered the first true modern diving watch, with an identity that has remained strongly linked to the marine world and the brand's professional collection. Its recognisable design, rotating bezel, meticulous legibility and construction designed for underwater use explain its lasting place on the pre-owned market in Europe. Values hold up well, as the Fifty Fathoms combines watchmaking heritage, relatively selective production and consistent demand for steel, titanium or limited-edition versions. The resale price depends mainly on the overall condition, the presence of the complete set, the precise reference, the case material and bracelet, as well as the rarity of the series. Well-preserved, serviced and documented versions easily find buyers among those looking for a prestigious diver's watch, both technical and historically significant.

Reading the Fifty Fathoms Blancpain price guide
The range observed for Fifty Fathoms Blancpain runs from €4,700 to €29,000, with a median of €11,600 — a 6.2× gap between entry-level examples and the most sought-after ones. That spread is normal: on this model, condition, material and year weigh more heavily than the reference itself.
In practice, a piece below the median usually shows accepted signs of wear or a common configuration; above it you find rare colours, precious hardware and complete sets with the original box and invoice.
What pushes the Fifty Fathoms price guide up
- Full set: box, warranty, spare links and original invoice
- Unpolished case, original edges and a dial with no relume
- Exact year and reference (dial transition, calibre)
- Recent service documented by an approved watchmaker
Selling a Fifty Fathoms Blancpain at the right price
We offer two options on this model. Outright purchase, settled within 72h once the piece is authenticated, suits anyone who wants an immediate exit. Consignment aims for the top of the range: the piece is photographed, promoted and sold with a commission that decreases with your membership card.
The pre-owned watch market has normalised since the 2022 peaks: steel sports references keep a premium, while gold and dress models currently offer the best entry points.
How we authenticate a Fifty Fathoms Blancpain piece
Every piece that joins Monogram Paris follows the same protocol in our Paris workshops: no catalogue photography, no supplier imagery, only shots of the actual item.
- Case and movement numbers recorded and cross-checked against the registers
- Dial, indexes and hands: printing, luminova and any relume documented
- Movement opened by a watchmaker: calibre, finishing, service parts
- Amplitude and instantaneous rate checked before listing
- Bracelet, deployant clasp and links inspected one by one
Care and storage
- Service recommended every 5 to 7 years depending on the calibre
- Water resistance test after every case opening
- Avoid magnetic fields (speakers, magnetic bags, tablets)
Buy, sell or request a valuation
Two routes: outright purchase, paid within 72h of authentication, or consignment, with a commission that decreases with your membership card (25% Blanche, 22% Or, 15% Noire).
On purchase, every piece ships insured within 10 to 14 business days, certificate of authenticity included. Our advisors answer any valuation request within 24h.
