Elevate your MoonSwatch with our premium 316L Stainless Steel "Speedmaster" Inspired Upgrade Case by Watchdives. Engineered to give your original timepiece the weight, durability, and classic aesthetic of an iconic steel chronograph, this conversion transforms your watch into a refined, everyday masterpiece.

Why Upgrade?

• Built to Last: Replaces fragile bioceramic with surgical-grade 316L stainless steel.
• Scratch-Resistant Sapphire: Upgrades the stock plastic crystal to a resilient bubble sapphire glass.
• Optional 1.5mm Flat Sapphire Crystal glass.
• Eliminate Weak Points: Resolves fragile pusher issues with sturdy, steel construction.
• Slim & Compact: The slimmest and smallest upgrade profile in our collection (41.5mm width × 12.9mm depth).

How Our Full-Service Conversion Works

When you order, our expert team handles the entire rebuild process for you:

1. Send Us Your Watch: Simply post your MoonSwatch to our UK workshop (instructions below).
2. Professional Extraction & Servicing: We safely uncase your movement, perform a full inspection, clean the components, and fit a fresh battery.
3. Precision Re-Assembly: We install your movement into the new stainless steel housing with your choice of bezel.

Customize Your Look

Select your preferred bezel option at checkout:

• Classic Black with white tachymeter markers
• Sleek Silver with black tachymeter markers

(Bracelets and custom straps are sold separately).

Important Notes & Guidelines

Service-Only Listing: You are purchasing the conversion service and steel case upgrade only. You must supply your own MoonSwatch.
Permanent Conversion: Uncasing the original movement renders the factory bioceramic housing unusable. We advise against attempting this modification yourself.
