While this is essentially just a new dial and a new bracelet, both have a decidedly large impact on the look and feel of the Overseas Perpetual Calendar Ultra-Thin. The blue is a bit more casual, with a youthful charm that looks to pair nicely with the available blue rubber strap. It’s hard to go wrong with blue and gold, and the dial’s translucent lacquered construction makes for an eye-catching shimmer of color, especially at the glass-like edges of the moonphase aperture.
