Rubber B’s SwimSkin Ballistic is listed for the Omega Seamaster 300 Heritage, not for every watch called a Seamaster 300. The maker describes it as a fabric-look, 100% rubber strap; the Omega buckle supplied with leather-strap models is not compatible. Check your exact watch reference and buckle setup with Rubber B before ordering.
Which Omega Seamaster 300 does the strap fit?
Rubber B’s exact product listing names the Omega Seamaster 300 Heritage. The company’s collection distinguishes “Omega Seamaster 300” from “Omega Seamaster 300 HERITAGE,” so the listing should not be read as a universal fit claim for every Seamaster 300 reference. See the Rubber B product listing and its Omega watchband collection.
A February 2024 Rubber B product list also separates Seamaster 300 and Seamaster 300 Heritage options and notes that some Seamaster 300 models might require curved pins. That document discusses other strap codes; it does not establish that this Ballistic Heritage strap fits other references. Ask Rubber B to confirm your watch’s exact reference and spring-bar setup before purchase.
Is the Ballistic strap Kevlar?
No. “Ballistic” describes the woven, fabric-like appearance. Rubber B says the strap is 100% rubber, not Kevlar textile. Its product specifications describe it as made in Switzerland from pure vulcanized rubber, with no coatings, blends or bonding.

Rubber B also says the strap uses “Blocked Integration” engineering, with solid inserts intended to create a flush, motionless fit against the case. The company describes it as waterproof for aquatic activities, including ocean and pool use, and says it meets FDA and BVGG specifications. Those are manufacturer claims; the cited product information does not provide independent material testing or confirmation from a standards body.
Does it include a buckle, and will the Omega buckle fit?
The strap listing says it is not compatible with the Omega buckle supplied with leather strap models. Rubber B offers an optional 18 mm fine tang buckle. The company says other standard 18 mm tang buckles with a similar hole post may also work, but that is not confirmation that any particular existing buckle will fit. Check the buckle dimensions and compatibility with Rubber B.

What to confirm before ordering
- Find the exact reference of your Seamaster 300 and ask Rubber B whether this Heritage-specific Ballistic strap fits it.
- Confirm the spring-bar or pin setup required for that watch reference.
- Decide whether you need Rubber B’s optional 18 mm tang buckle; do not assume the Omega leather-model buckle will work.
- Check the current color, wrist sizing, price and availability on the product page.
