Peter Speake-Marin has completely redesigned the Spirit Pioneer model using a new case, dial and movement. The dial alone is as complicated to produce as an enamel dial, requiring the use of different moulds to produce a face that can be bonded to a traditional dial plate. The finished dial has bold Roman numerals, hour markers and minute track in SuperLuminova, producing a clearly readable display when viewed against the light-absorbing matt black background. The 42mm case in stainless steel houses a new TT738 calibre movement with unidirectional automatic winding that offers a 120-hour (5 day) power reserve.
