The IWC Da Vinci Automatic 40mm is the one IWC dress watch that doesn't ask you to explain yourself at a dinner table. At 40mm, it fits a wrist without ceremony. The caliber 35111 inside is a Sellita SW300-1 base, which keeps the price honest, and the round case with a sapphire exhibition back gives you something worth looking at when the conversation slows.
IWC revived the Da Vinci name in 2017 after the previous generation had drifted toward large, complication-heavy references that attracted limited audience. The IW356601 marks the return to a simpler premise: a 40mm round dress watch in steel, with IWC catalog-standard complications kept to a date at 3. The caliber 35111 designation is IWC-finished Sellita SW300-1, a movement architecture shared with the Portofino line.
IWC has offered the Da Vinci in silver, blue, and black dial variants, with the blue dial drawing the most attention on the secondary market. No significant revisions have occurred since the 2017 relaunch; the case geometry and movement specification have stayed consistent.
The Sellita base movement is not a flaw, but buyers expecting in-house manufacture should look at the Portugieser or Big Pilot 43 before committing. The 30m water resistance is nominal; do not take this watch swimming. Check the date quick-set on any pre-owned example, as the Sellita SW300-1 date corrector can feel imprecise and any roughness suggests a service is overdue.
Exhibition caseback glass scratches more readily than solid casebacks, so inspect it carefully; polishing requires factory tools. The Da Vinci competes against Longines and Tudor dress references at similar price points, so the IWC name is part of what you are paying for, and that premium should be assessed honestly.
