Vacheron Constantin lists a 40-hour power reserve and 3 bar (30 m) water resistance.

Which Fiftysix Day-Date is this?
This review concerns the stainless-steel Fiftysix Day-Date, reference 4400E/000A-B437. It is distinct from the simpler steel Fiftysix self-winding ref. 4600E/000A-B442 and the pink-gold Day-Date ref. 4400E/000R-B436. Vacheron Constantin says the design honors a 1956 model, with case horns inspired by the sides of the Maltese cross. Vacheron Constantin’s product page identifies the reference and describes the design; the steel model also appears in the brand’s 2025–26 catalog.

What the design and displays mean in daily use
A layered, restrained dial
The grey dial’s contrasting centre and outer finish add texture without changing its subdued overall character. Day and date appear in separate counters, while the power-reserve display adds another indication. The hands and markers use blue Super-LumiNova, but the brand’s specification alone does not establish how legible the displays are in every lighting condition.
#1 Best Overall
- Selected calf leather, leather shoes feel soft and comfortable, and the body of the watch as one!
- The bottom leather is comfortable, soft, breathable, waterproof and sweatproof, which can effectively resist the erosion of sweat and prevent odour.
- The clasp is made of 316 stainless steel, polished meticulously and stable without fading.
- Please measure the lug width before ordering, the lug width must be exactly the same as the selected strap width to ensure accurate wearing.
- A set of matching spring bars and installation tools are included.
More information, with a modest reserve
The calibre 2475 SC/2 brings day, date and power reserve alongside the time. Its stated 40-hour reserve is a practical ownership consideration: if the watch is left unworn beyond that period, it will need resetting before wear. The specification provides no independent measurement of real-world running time.
Case dimensions and water rating
At 40 mm across and 11.6 mm thick, the published dimensions give a concrete basis for judging fit, but wrist presence depends on the wearer and cannot be established from measurements alone. The 3 bar (30 m) rating is the published water-resistance figure; it should not be taken as evidence that this watch is suitable for swimming or diving.

Price and the secondary market
As of October 2026, WatchCharts’ UK reference page listed £26,300 as retail price and £10,387 as a market price estimate. These are UK-specific guide figures, and the estimate can change; it is neither an offer nor a guaranteed realized value. WatchCharts’ figure should not be treated as official global pricing.
Chrono24’s listings for ref. 4400E/000A-B437 show active offers, but asking prices are not completed-sale prices. Listings can differ by condition, what is included, seller and location. Monochrome reported an original launch-era price of EUR 17,300 including tax; that is historical context, not a current price. Monochrome’s review discusses the launch-era watch.

What to check before buying pre-owned
Because an asking price does not confirm condition, value or authenticity, assess the individual watch and transaction rather than relying on a reference-level estimate.
- Condition: Inspect the case, crystal, dial, hands, strap and clasp, and ask whether any damage or replacement parts are documented.
- Set contents: Confirm whether the box, papers and other original accessories shown or promised are included.
- Service history: Request available service records and clarify what is known about the watch’s maintenance.
- Seller and protections: Check the seller’s reputation, authenticity process, return terms and buyer protections before paying.
- Total cost: Confirm taxes, shipping and any other charges for your location; marketplace offers can vary geographically.
Who should consider it?
The steel Day-Date is a considered option for someone who wants a restrained grey-dial watch with day, date and power-reserve indications in one design. Its trade-offs are equally specific: the extra displays add information to the dial, the stated reserve is 40 hours, and the published water resistance is 3 bar / 30 m. Whether it makes sense at a particular price depends on the individual watch’s condition, completeness, service provenance and seller protections—not on a market estimate alone.
