The 2021 launch coverage reported black and blue versions, each limited to 100 pieces, at a launch price of €6,450. That dated launch figure is distinct from later seller displays: Graham’s archive page showed the blue model at $7,950 and sold out, while a Swiss retailer listed it at CHF 7,450.
What makes the Fortress a monopusher chronograph?
Instead of separate chronograph buttons, the Fortress uses one pusher built into its crown on the left side of the case. Graham describes the control as operating the chronograph’s start, stop and reset functions. The left-side placement allows operation with the thumb.

Launch coverage describes the G1750 as based on the Valjoux 7750 and using a cam-actuated chronograph. Graham’s specification page confirms the G1750’s technical details but does not state its base calibre.

References and limited-edition quantities
Monochrome Watches’ 22 July 2021 launch report identified two dial-color references. Each was reported as a 100-piece limited edition.
| Launch variant | Reference | Reported edition size |
|---|---|---|
| Black | 2FOAS.B01A | 100 pieces |
| Blue | 2FOAS.U01A | 100 pieces |
The edition quantities and reference pairing are reported in Monochrome Watches’ 2021 launch coverage. Graham’s Japanese Fortress collection page later listed the black 47 mm 2FOAS.B01A as limited to 100 pieces; its displayed price was dated May 2024 and is specific to that regional listing.

There is no single price that can be treated as a universal current price from these listings. The figures below refer to different dates, currencies and seller contexts.
| Price displayed or reported | Context |
|---|---|
| €6,450 | Launch price reported by Monochrome Watches in 2021. |
| $7,950 | Graham’s archive page for blue Fortress 2FOAS.U01A-1, accessed 7 October 2026; the page marked the product sold out. This display does not establish current stock. |
| CHF 7,450 | Uhrenschmuck24 / CHRISTIAN AG listing for the blue limited edition, accessed 7 October 2026, with a stated delivery estimate of 4–6 weeks. Retailer pricing and availability may change. |
Graham’s Japanese Fortress collection page listed the black 2FOAS.B01A at ¥1,028,500, with prices stated as of May 2024. The page notes that buckle configuration can affect price, so this regional listing should not be treated as a conversion of the 2021 euro launch price.
Quick Recap
What to check when comparing a listing
- Confirm the reference and dial color: black 2FOAS.B01A or blue 2FOAS.U01A in the reported launch configuration.
- Read the price in its listed currency and note its date; a launch report, an archive display and a retailer offer are not equivalent price evidence.
- Check whether the page says in stock, sold out or gives a delivery estimate. A displayed price alone does not confirm availability.
- Verify whether the seller is offering the exact watch and what condition it is in; the cited price displays do not establish a complete current-market comparison.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
