40.5mm Carbon Case, 38mm Grade 23 Titanium Core: Apiar Carbon1.0 OG Debuts CBAM Construction
40.5mm carbon-fiber outer case surrounds a 38mm Grade 23 titanium core on Apiar’s new Carbon1.0 OG. The UK brand uses a Composite-Based Additive Manufacturing (CBAM) process to deliver hybrid carbon-titanium construction.

40.5mm carbon-fiber outer case, 38mm Grade 23 titanium core
Apiar’s Carbon1.0 OG pairs a 40.5mm carbon-fiber outer shell with a 38mm Grade 23 titanium core. That hard fact is the central technical claim behind the watch: a hybrid structure rather than a single-material case.
CBAM: a new approach to carbon-composite watchmaking
The watch is built using Composite-Based Additive Manufacturing (CBAM). Apiar calls this a different way to form carbon-composite parts. The brand is UK-based and positions the Carbon1.0 OG as its first sports watch. As Fratello Watches – The Magazine Dedicated To Luxury Watches first reported, the CBAM process is the headline rather than a conventional forging or layered-carbon method.
The hybrid assembly lets Apiar pursue openworked forms. The outer carbon shell and inner titanium core separate structural duties: the carbon provides the sculpted exterior, the Grade 23 titanium serves as the load-bearing chassis. Apiar uses that split to create more ambitious case geometry than you normally see from single-piece carbon cases.
- Case: 40.5mm carbon-fiber outer case
- Core: 38mm Grade 23 titanium core
- Manufacturing: Composite-Based Additive Manufacturing (CBAM)
- Brand: Apiar, UK-based; model: Carbon1.0 OG
The source piece does not publish movement, power reserve, finishing details, water resistance, or pricing. Those are open questions until Apiar supplies full technical specifications and availability.
What to watch next: confirm the movement, check how the brand bonds or tolerances the carbon to titanium, and test finishing and wear comfort on the wrist. If CBAM performs as suggested, other small brands could copy the hybrid route to get carbon looks with a metal backbone — but we need hands-on tests before calling it a game-changer.
