Maxima GR8 Incolor Sapphire Ultraviolet

Kerbedanz unveils a striking new expression of the Maxima GR8 39mm at Milano Watch Week 2026, pairing its transparent incolor monocrystalline sapphire case with an entirely new Ultraviolet dial.

At its centre, the one-minute flying tourbillon remains the defining feature, surrounded by a peripheral hour and minute display. The vivid ultraviolet tone appears suspended within the transparent architecture, creating a constantly changing interplay of colour, light and mechanics.

Powered by the automatic KRB-13 calibre, the timepiece delivers 65 hours of power reserve.
