In Context

909010LN-0001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black gloss dial with a ceramic, stainless steel case.

Quartz movement with an analoog display on the front for the hours, minutes, seconds and date, and a digital display on the back for the (secular) perpetual calendar.
