When I say "perpetual calendar," this probably isn't what comes to mind. You're likely imagining something like the ceramic Royal Oak Perpetual calendar or the more traditional Patrimony Perpetual. But this little desk-top device of the same name is a manual timekeeper that the user sets each morning and then references throughout the day. It's called a perpetual calendar because, in theory, it will work forever. The Perpetuum Calendar comes to us from 3D-printed design firm OTHR and Spanish designers Studio Yonoh and it's about as cool a balance spring-free perpetual calendar as you'll find anywhere.
ADVERTISEMENTIn case you're not familiar, OTHR launched last year and is essentially a manufacturer that works with designers to create 3D-printed products on order. The goal is to reduce waste and cost by cutting overhead and excess production, and the firm's aesthetic sits firmly in the modern and minimal camp. These aren't cheap plastic matrix objects either ?OTHR 3-D prints with materials like bronze and porcelain and all the objects are finished by hand after they come off the printers.
The gold-plated markers sit on a 3D-printed base.
The Perpetuum Calendar was designed for OTHR by Studio Yonoh, a practice based in Valencia, Spain, and founded in 2006 by Clara del Portillo and Alex Selma. The way it works is pretty simple. You have two tracks, one for the month and one for the day. Each has a moveable marker that you slide into place at the beginning of each day. This isn't a piece of high-tech horology here. The profile is inspired by early industrial factories, with the sawtooth shapes doubling as functional slots for the two gold-plated markers, and the spare, graphic display is meant to be readable at a quick glance.

The Perpetuum Calendar comes in two versions. The first has a grey metallic plastic base and 14k gold-plated markers for the month and day, while the second has a jet black nylon base and the same gold-plated markers. Like all of OTHR's products, they're 3D-printed and then hand-finished to order, so you're looking at about two to three weeks production time on either color. The pieces are individually numbered in the order in which they're made, so order quickly if you want a low number.
The Perpetuum Calendar is small enough to fit nicely on many different kinds of desks.
The black Perpetuum Calendar retails for $470, while the grey version retails for $510. You can order directly from OTHR online.
