How to use: you only need to fix the watch on the maintenance stand or hold it tightly, and then roll the adjusting wheel to set it to the position that matches the cover of the watch. After the case is opened, turn the back cover of the watch to open the back cover. Review: Great choice - These tools work fine for most applications. I needed the ability to open larger case backs up to 45mm and this purchase solved my problem! Review: Better than the other types - 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. ## Features - Case opener: the case back cover opener can easily remove or tighten the waterproof case back cover to replace the battery or repair the watch.

I have several large 45-50mm watches and the standard 3 prong case opener was too small. These work great but the build quality is a bit low. They work, but the pins rotate a bit even though they are slotted to pit the bar/handle. Again, good for the price. ## 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? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/340311778-mudder-2-piece-adjustable-watch-back-case-opener-kit-stainless](https://www.desertcart.dk/products/340311778-mudder-2-piece-adjustable-watch-back-case-opener-kit-stainless) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-04-28*
