Master of Days Mechanical Calendar Cufflinks
Indie watchmaker Konstantin Chaykin has created a pair of mechanical cufflinks that function as a seven-day calendar. The wearer advances the day display by fastening the cufflinks, integrating the act of getting dressed into the mechanism's operation.

Each cufflink features a miniature 18mm-diameter, 5.7mm-thick titanium case with a sapphire crystal and anti-reflective coating, housing an elaborate mechanical device.
The mechanism includes a seven-pointed star wheel at the center, which drives a bright blue pointer to indicate the current day of the week.
The calibre A.01-1 movement measures 13.9mm by 2.1mm and is built with two jewels, with finishing inspired by fine watchmaking, including sandblasted mainplates, brushed and polished components, and hand-finished anglage.
Each cufflink is comprised of 40 components in total: 13 for the case and 27 for the display mechanism.
