3D Printable Urwerk UR-220

A functional wall clock interpretation of Urwerk's UR-220 that can be printed on a typical, filament-based, consumer-grade, 3D printer.

Liquid Clock

An open-source, ferrofluid-based display created by students at the University of Oslo.

I applaud the students' persistence in striving to achieve a long-lasting ferrofluid display. Having had the opportunity to work with ferrofluid in glass on several occasions, I'm well aware of just how much of a challenge this poses.

A Breguet Fit for a Duke

Owned by Charles Félix, the Duke of Choiseul-Praslin, in France, this double-sided pocket watch crafted by Breguet features a retrograde perpetual calendar, equation of time, and moonphase display.

A patron and benefactor of Abraham-Louis Breguet, Charles Félix financed the watchmaker's work on multiple occasions. He acquired this particular timepiece in 1805. It now resides in the collection of the Musée des Arts et Métiers, in Paris.

Day's Eye

Our modern English word for ‘daisy’ comes from the Old English dæges-eage, meaning ‘day’s eye’.

CYPHER_WATCH

A cyberpunk timepiece, created by Max Braun and Kateryna Romanova, that bridges the real and digital worlds.

CT Scan of a Lego Minifig

The World's Smallest Orchid Blossom

Nearly transparent and standing in at just over a millimetre across in full bloom, this yet-to-be-named orchid, which is part of the Platystele genus, was discovered by Lou Jost, in Ecuador.

SuSoS AG

This tiny, privately held, Swiss company supplies Rolex with its proprietary, non-toxic, epilame surface treatment.

SuSoS's PAcrAm technology provides a convenient and highly tuneable, dip & rinse solution to finely control surface energy using monomolecular thin-films. For the purposes of mechanical timekeeping, that surface energy is tuned to keep lubricant precisely where it is supposed to be.

Based in Zurich, the firm was initially spun up as SurfaceSolutionS GmbH in 2004 (not to be confused with the Austrian firm Surface Solutions GmbH founded in 2020) and later shortened to SuSoS circa 2007. It is ostensibly associated with Rolex SA's tribological research and development division, as the company's directors, Samuele Tosatti and Stefan Zürcher, are the only names on the 2006 patent (EP1927648A1) assigned to Rolex for said surface treatment, which also happens to make extensive use of the term SuSoS to refer to the various epilame formulations that it details. This patent was later withdrawn and superseded by another, assigned to both SuSoS AG and Rolex SA, in 2011.

In their own words, SuSoS focuses on the 50 nanometers that make the difference.

Under the Dial of a Movado Polyplan

One of very few curved watch movements to ever enter into mass production.

TrueDome

Fabricator of period-correct reproductions of vintage Rolex watch crystals, founded by New York City-based, psychologist-turned-watch-repairer, Greg Petronzi.

Certina DS+

A novel spin on the original Certina Double Security, first introduced back in 1959.

Serving up six different case configurations and multitude of strap options in a single watch, each case outer is securely affixed to the swappable inner core through the combination of a bio-sourced gasket and double-crown system.

Making Magic Gold

Ripley Sellers goes behind the scenes at Hublot to tour their manufacturing facilities and offer some insight into their process for creating coloured ceramics, including their scratch-resistant, 18 carat Magic Gold that relies on a similar method of fabrication.

Charles Emslie's School Watch

Emslie recounts for Hodinkee the school watch that he made during his time at the Lititz Watch Technicum.

"Early mornings and late nights defined my life for two whole years; each new day represented a new lesson that built on the skills born from the previous day's work."

"Each mistake—made and then corrected—added to the watch's story."

The click for the ratchet wheel, inspired by a 1920s-era E. Howard & Co. pocket watch owned by his great-great-grandfather, is a subtle and welcome change to the standard fare found on most movements derived from the Unitas 6497.

Bangerter Microtechnik AG

With its core strengths centered around precisely crafting strong materials, Bangerter serves as a key manufacturer and supplier of tungsten carbide and hard ceramics for the Swiss watch industry, including the likes of Audemars Piguet and Richard Mille.
