The movement in this piece is your hand-wound IWC caliber 94805, which beats at a leisurely 2.5Hz and comprises 96 hours of power reserve.

Founded in 1868, IWC prepares to celebrate its own 150-year history in 2018 with five restricted models from different collections, along with the IWC Da Vinci Automatic Edition “150 Years” watch is the most accessible among them. Apart from the “150 Years” from the titles, all share the lacquered dial with printed numerals — all white except the Da Vinci Automatic you watch here in blue. This isn’t simply a “small-seconds” version of last year’s three-hand Da Vinci Automatic (hands-on here), since it represents an in-house movement alternative with a fresh member of IWC’s 80000 family of movements.The Da Vinci has gone through a number of redesigns because it premiered in 1969, housing the initial Swiss quartz movement, the Beta 21. IWC reimagined the Da Vinci collection last year to re-introduce a round Da Vinci case silhouette with notable articulating lugs. 1 thing I can say for the new Da Vinci watches is that articulating lugs are often something I love, however — and perhaps it’s just me — it seems like the dressy, controlled character of this round Da Vinci is currently fairly well represented at IWC by the Portofino and Portugieser collections.
