Thanks in advance** A: I wouldn't bother. These are not really made for watches and I was unable to get them to work on any of my watches. They are too thin, in my opinion. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by B***E on October 5, 2018* This is very good and a good price, it would be better if it had larger sizes ... ### ⭐⭐⭐⭐⭐ Watch back o-rings *by D***R on December 29, 2023* Many sizes and works great ### ⭐⭐⭐⭐ Seems like the right part for my watch *by M***E on April 27, 2018* Seems fine as far as I - a non-watch maker - can tell. I only needed one gasket (but got 950 and now have 49 *extra* of the one size I needed lol) but according to the Seiko site this gasket is not only the right diameter but also roughly the same width (.5mm vs the "real" Seiko spec of .4mm). I do like that each of the sizes are pre-sorted as a few others I looked at seemed like a random mess. I guess time will tell how well it holds up but as this watch is not really designed for swimming/diving the water resistance is just for splashing while washing hands, sweaty wrist, rain, etc. Fingers crossed for longevity! --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/30066355-vapker-950-pcs-o-ring-0-5mm-watch-back-rubber](https://www.desertcart.ph/products/30066355-vapker-950-pcs-o-ring-0-5mm-watch-back-rubber) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-10*
