I ordered these on Amazon and removed the battery cover without a problem. If there's one drawback, you have to get used to sizing the teeth to the cover but once you do, the back cover comes out pretty quickly. This little tool is very good and gets the job done quite nicely. ### ⭐⭐⭐⭐⭐ Better than the other types *by on Reviewed in the United States May 27, 2022* People should be aware that the 3 point type included in most of the watch tool kits is the (((small))) version that won't fit cases larger than 42 mm. (Guess how I found out...) Unless the kit specifically says you are getting a large case back opener assume it's a small one.Overall that 3 point type just looked like a problem waiting to happen. Too many moving parts and poor quality parts. Do I just order a bigger one? Umm... no.Then there is the 2 point with a thumbscrew to adjust the width. Not enough leverage there, having to twist it between your thumb and index finger. And it doesn't appear you can lock the width in place. So... no.Glad I got this one. Simple, with a substantial handle to apply as much leverage as you need without losing control of the tool. And sometimes you need a lot of leverage.My only complaint - and others have noted - is it can be a bit fussy tightening the adjustment screw and not misadjusting the width you want in the process. You may have to adjust and tighten more than once to get it right. Once you do you have a rock solid tool at just the right width.Missing parts? Mine didn't have missing parts but the smaller one came unassembled. So you screw the part in place. Did youse people check the bag for that part? I doubt you will ever need to use the smaller one anyway.I like it. No regrets. ### ⭐⭐⭐⭐ works well, needs a vice or clamp *by on Reviewed in the United States July 15, 2026* need to buy a kit with a clip or clamp unless you have one ## Frequently Bought Together - Mudder 2 Piece Adjustable Watch Back Case Opener Kit Stainless Steel 58 mm and 50 mm Alloy Wrench Type Watch Back Cover Opener Remover Tool for Battery Replacement Repair - LiCB 20 Pack SR920SW 371 370 AG6 Battery 1.5V Button Cell Watch Batteries --- ## 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.kg/products/340311778-2-piece-adjustable-watch-back-case-opener-kit-stainless-steel](https://www.desertcart.kg/products/340311778-2-piece-adjustable-watch-back-case-opener-kit-stainless-steel) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-08-15*
