4 reviews for 21mm Fitted Rubber Replacement Strap

  1. Richard Rajchel

    5 for quality, but did not fit the watch I bought it for.

    Unfortunately this does NOT fit on the 41mm Datejust (at least not my 2025 model with the Jubilee bracelet and fluted bezel). Please take note. It is a good quality strap and would have looked amazing if it would have fit, but despite the description saying it fits the 41mm Datejust it likely only fits certain vintages or perhaps with an oyster bracelet from the factory. I’m not familiar enough if the Oyster bracelet comes with a different shaped case/endlinks or not, but the 2025 Fluted bezel jubilee bracelet model is not a fit unfortunately. Loved the strap, but didn’t fir.

    Installed On: Rolex Datejust 41mm 2025 model with Jubilee bracelet and fluted bezel.

    This rubber strap is fantastic and it looks amazing on my GMT. It’s super comfortable to wear. I did have a bit of trouble installing it at first, but once I got past that, it fit perfectly and feels great on my wrist.

    I got this strap for my sport model Rolex watch with a ceramic bezel, and it’s a perfect match! TIP: It also fits some other Rolex models and even non-Rolex brands. I’m extremely satisfied with the quality and fit.

  4. John Poulsen

    Almost a perfect fit for my Rado 43mm High-Tech Ceramic Captain Cook. I did manage to make it fit using a very sharp pointed exacto knife to shave off a tiniest bit of rubber of the curved end lugs(from the underside-the curve profile did not need shaving). Once that was done; it looked the part!
