Apple Watch Case, Polycarbonate 49mm Ultra-Style Profile Converter

This polycarbonate shell does one job well: it takes the Apple Watch case you already have — anywhere from 40mm to 46mm, across Series 4 through Series 10 and SE — and wraps it into the same 49mm silhouette as the flagship Ultra. The bezel is cut narrow so the display still reads edge-to-edge, and the curved half-wrap shape hugs the case instead of boxing it in.

Features

• Polycarbonate build — lightweight, durable protection without adding real bulk to your watch.
• 49mm size conversion — reshapes 40mm through 46mm Apple Watch cases (Series 4–10, SE) into one unified 49mm profile.
• Narrow bezel — kept slim so the display stays visible right to the case edge.

Fitting it

The curved half-wrap design lines up its side openings 1:1 with your watch's crown and power button, so fit it carefully: once it's on, check that the crown still turns freely and the power button presses without resistance before you wear it.

Frequently asked questions

Does this fit the Apple Watch Ultra itself?
No — it's designed for the standard Apple Watch (Series 4 through 10, and SE) in 40–46mm cases, and gives them the Ultra's 49mm profile.

Will the Digital Crown still work normally?
Yes, once it's fitted correctly. The side openings are cut to a precise 1:1 match with your watch's crown and power button, so both operate without added resistance.

What finishes are available?
Four: Titanium, Silver, Black, and Starlight.
