Its product listing identifies versions for PRX 35 mm, 38 mm and 40 mm models; Delugs describes the moulded fit as flush with those cases. That is the maker’s design claim, not an independent fit test or a guarantee for every watch. Check your PRX’s exact case size and the live product selector before ordering.
Which Tissot PRX sizes does the Delugs strap fit?
Delugs’ current product page identifies CTS strap options for the PRX 35 mm, 38 mm and 40 mm. The page’s availability statement, dated 5 March 2026, names Black, Navy and White; colours and stock can change. Check the size and colour choices on the live listing before purchase: Delugs Tissot PRX CTS rubber strap.
Delugs’ support FAQ also names the 42 mm PRX Chronograph, but the current product listing does not include that size in its stated availability. Confirm directly in the selector that a 42 mm option is offered before ordering. Delugs says the straps are not compatible with other Tissot models; its FAQ describes them as specifically crafted for PRX 40 mm, 35 mm and 42 mm Chronograph cases. These are manufacturer compatibility statements, not independent measurements: Delugs compatibility FAQ.
Read the size printed for your watch or check its model details rather than assuming that a strap listed for one PRX will work on another. The 35 mm, 38 mm and 40 mm versions are distinct fit options.

What Delugs means by a flush fit
The strap is shaped for the PRX case rather than presented as a generic straight-ended rubber strap. Delugs says its model-specific moulding provides a flush fit. That supports describing it as a dedicated PRX design, but it does not establish a measured fit rate, performance across production variations or a comfort advantage. No independent fit or durability test is cited here.
Delugs says it developed the strap independently and is not affiliated with Tissot. It is an aftermarket product, not a Tissot-made strap.

How the CTS strap and clasp work
CTS means “cut to size”: the strap starts as a universal length and the wearer trims it to fit their wrist. Delugs’ support FAQ says it is used with a leaf-spring deployant clasp, rather than a conventional fixed-length strap with a tang buckle. Delugs gives a maximum length of 103 mm on each end and advises cleaning the rubber with a damp cloth. Those are manufacturer specifications and care guidance; follow the supplied product instructions when cutting.
Clasp sizes Delugs specifies
| PRX size | Clasp size in Delugs’ FAQ | What to check |
|---|---|---|
| 40 mm | 18 mm deployant clasp | Confirm the current clasp compatibility and whether it is included or selected separately on the product page. |
| 35 mm | 16 mm deployant clasp | Confirm the current clasp compatibility and whether it is included or selected separately on the product page. |
| 38 mm | Not stated in the cited FAQ | Check the live product selector or ask Delugs which clasp option applies. |
| 42 mm Chronograph | Not stated in the cited FAQ | First confirm that a 42 mm option is currently offered, then confirm clasp details with Delugs. |
The clasp information comes from Delugs’ support material, which may not reflect later product changes. Consult the Delugs PRX rubber CTS FAQ alongside the live listing rather than assuming every size has the same clasp or package contents.

Installing the strap on a PRX bracelet
Delugs says quick-release spring bars are included and that installing the replacement strap does not require a tool. If your PRX is still on its factory bracelet, removing that bracelet may require a spring-bar or bracelet-removal tool. Delugs’ PRX 35 mm strap guide discusses bracelet removal separately from fitting the quick-release strap. Avoid forcing a tool against the case; if you are unsure, have a watchmaker remove the bracelet.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Delugs versus Tissot’s official rubber strap
Tissot lists a separate official blue rubber strap, product number T852049577, as compatible with all 40 mm PRX models on its US site. That listing establishes an official option for 40 mm models, not for other PRX sizes. It is a different product from Delugs’ CTS strap; compare the exact size, adjustment system, clasp and included hardware on each manufacturer’s page before choosing.

What to verify before ordering
- Match the strap option to your exact PRX case size, not simply the PRX name.
- For a 42 mm Chronograph, verify current availability with Delugs; the FAQ and current listing name different size ranges.
- Confirm clasp compatibility and whether the clasp is included or must be chosen separately.
- Check current colour and stock, since Delugs’ dated 5 March 2026 availability statement may change.
- If keeping the original bracelet, plan for its removal; the quick-release strap installation itself is described by Delugs as tool-free.
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.
