The Forstner Model J is an aftermarket Jubilee-style bracelet for selected Tudor Black Bay models—not a Tudor factory bracelet. Its fit depends on the exact watch: Forstner lists a 20 mm version for the Black Bay 58 and Ranger 39, and a 22 mm version for the Black Bay, Black Bay GMT, and Black Bay Chronograph. It excludes the Black Bay Pro, Black Bay 58 GMT, and Black Bay 54. Check your exact reference against the current Forstner listing before ordering.
Which Tudor Black Bay models does the Forstner Model J fit?
Forstner lists two sizes for selected watches. The family name alone is not enough to establish fit, and compatibility should not be assumed for every Black Bay generation or variant.
| Forstner size | Models listed as compatible |
|---|---|
| 20 mm | Tudor Black Bay 58; Ranger 39 |
| 22 mm | Tudor Black Bay; Black Bay GMT; Black Bay Chronograph |
| Not compatible | Black Bay Pro; Black Bay 58 GMT; Black Bay 54 |
These model listings are from Forstner’s product page. If your watch is a less common reference or generation, confirm the reference and the live listing before purchase rather than relying on “Black Bay” as a general fit label.
What is the Model J bracelet like?
Forstner describes the Model J as a Jubilee-style bracelet made from solid 316L stainless steel, including a solid steel end piece. Its inner links are polished, its outer links brushed, and the bracelet sides polished. The links use a single-screw system for sizing.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
The bracelet tapers from the selected 20 mm or 22 mm end piece to 16 mm at the clasp. Forstner gives the clasp width as approximately 18.5 mm. These are manufacturer specifications, not independent measurements.
How does sizing and clasp adjustment work?
Links can be removed with the screw system. Forstner says the milled, push-button clasp has tool-free adjustment. The product page estimates an adjustable bracelet length of approximately 120–180 mm and a wrist range of about 6–8 inches; these are estimates, not a fit guarantee for every wrist shape or preferred wearing style.

Tudor lists a satin-brushed three-link steel bracelet and a brushed-and-polished five-link steel bracelet for the Black Bay family. Tudor describes its T-fit clasp as tool-free, with five positions across an 8 mm adjustment window. The Model J is a separate aftermarket bracelet with its own clasp; it is not Tudor T-fit.

- Review current availability and package contents. Stock, price, and included items can change; consult the live product page before checkout.
