From a movement and case perspective, nothing has changed from the original Felix and Erwin. Both remain 38.5mm in diameter, with the cases made in stainless steel. The Felix is still powered by the in-house Habring² A11B (time only, with sub-seconds) and the Erwin by the Habring² A11S (time only with deadbeat seconds). The changes comes on the dials, where instead of the grained and satin looks we saw on the Felix and Erwin, there are all new white dials inspired by marine deck watches, which were used to reference time against the marine chronometers onboard older vessels at sea.
