Carbon Fibre and Titanium Mod Kit for Apple Watch Ultra — 49mm Armour Case and FKM Strap
A carbon fibre and titanium alloy modification kit for Apple Watch Ultra 49mm — an armour-style case frame with carbon fibre-textured front surface, titanium alloy side details and exposed screw-style accents, paired with a fluororubber (FKM) strap with a metal folding clasp. The kit significantly increases the visual and physical presence of the Apple Watch Ultra. Apple Watch not included.
Variant note: Some options are band-only; others are case + band sets. Check the specific variant name carefully before ordering — band-only variants do not include the case frame.

This kit is for Apple Watch Ultra (49mm) only. It is not compatible with standard Apple Watch Series models. If you have a Series 9/8/7 or SE, see the Stainless Steel Mod Kit instead.
Variant System — Band-Only vs Case + Band
The listing offers two types of variants:
Band-only variants (e.g. WB-only Band, OB-only Band) — fluororubber strap only, no case frame included.
Case + band set variants (e.g. Black-BB, White-SS, Orange-RG) — case frame and strap included together.
The two-letter suffix indicates the combination:
- First letter/s: strap colour (W = white, B = black, O = orange, R = red, Gr = green, etc.)
- Second letter/s: hardware/case colour (B = black, S = silver, RG = rose gold, G = gold)
Confirm the specific variant type from the listing before ordering — band-only variants at different price points do not include the case frame.
Carbon Fibre Surface and Titanium Alloy Sides
The case frame uses two distinct materials:
Carbon fibre front surface: The textured woven carbon fibre pattern covers the front bezel face — creating the distinctive diagonal weave appearance and providing lightweight rigidity. The screw-style accents sit in this surface.
Titanium alloy sides: The case sides and hardware use titanium alloy — corrosion-resistant and significantly lighter than stainless steel for equivalent strength. The side cutouts expose the Apple Watch Ultra’s crown and side button.
The combination creates the armour-style silhouette: wide, rugged and heavily structured relative to the Apple Watch Ultra’s original profile.
Fluororubber (FKM) Strap
Fluororubber — also known as FKM or Viton — is the same strap material used in high-specification dive and sport watches including several BERNY divers and Steelflier models at Jewelry Addicts. FKM is resistant to sweat, oils, saltwater and UV degradation, making it appropriate for the Ultra’s active use context. The moulded sporty design includes adjustment holes. The strap can be trimmed to length for smaller wrists within the 160–220mm range.
96.6g — The Weight Trade-Off
At 96.6g including the strap, the mod kit adds significant mass to the Apple Watch Ultra’s base weight. The Apple Watch Ultra itself weighs approximately 61g — the combined kit + watch is approximately 158g. This is heavier than most mechanical watches but appropriate for buyers who specifically want the armoured, high-presence wrist character.
Open Back Sensor Access
The case frame’s open back design exposes the Apple Watch Ultra’s rear sensor array — heart rate, blood oxygen and other health sensors remain unobstructed and fully functional when the kit is installed.
Who Is This Mod Kit For?
This kit is built for:
- Apple Watch Ultra owners who want an armoured, rugged case character beyond the Ultra’s standard profile
- Carbon fibre and titanium material buyers who want these materials on an Apple Watch aesthetic
- FKM strap buyers who want the chemical-resistant sport strap on their Ultra
- Colour customisation buyers — the wide variant range allows specific hardware and strap colour combinations not available from Apple
How It Compares
vs. Stainless Steel Mod Kit (Series 4–11, SE) — The stainless steel kit fits standard Apple Watch Series 4–11 and SE (40/41/44/45mm). This carbon fibre kit fits Apple Watch Ultra only (49mm). Different case aesthetics — metal dress vs carbon armour.

Thank you a lot! Absolutely 5 stars!!!
I acquired my order in six days and I couldn't be happier! It turned to be absolutely high-quality. I had never witnessed something like it by that day. I'm so fortunate I stumbled upon it though, because it is good! Now this is possibly my best-loved product and prime marvel that I have had from ordering in the internet. If I could rank this item better than 5 stars, I would. I'm convinced I'll continue to enjoy it.
