In collaboration with Musée International d’Horlogerie (MIH), Zenith introduces the Captain Winsor Annual Calendar Chronograph. The Captain Winsor features Zenith’s famous El Primero chronograph caliber, with the addition of new complication, the annual calendar. An annual calendar displays the date, day of the week and month with only one adjustment required per year.

The exclusive 29-jewel El Primero 4054 automatic movement runs at 5 Hz (36,000 vph) and has a power reserve of 50 hours. Functions include hours, minutes, seconds, chronograph, annual calendar (date, day month).

The 42 mm diameter case comes in stainless steel or 18k rose gold. The case and bezel are brushed. The crown and pushpieces are polished. A box-shaped sapphire crystal with anti-reflection treatment on both sides protects the dial. A transparent sapphire crystal case back allows a view into the highly finished in-house movement, as well as the oscillating weight that is finished with Geneva stripes.

The dial comes with a silver-toned guilloché center and silver-toned circular satin-brushed exterior (stainless steel or rose gold) or a grey-toned guilloché center and blue-toned circular satin-brushed exterior (stainless steel – pictured).

Water-resistance is 50 meters. Black or brown alligator strap with protective rubber lining, rose gold or steel pin buckle.

A Swiss made in-house mechanical chronograph movement with annual calendar for under ten grand, is a pretty good deal. Retail price is $8,700 is stainless steel and $18,800 in gold.
