Pheidippides is back with another project, The Hourglass Watch. Last project we got a look at was The Porthole, a still amazing watch made out of bronze. The Hourglass Watch uses the concept of the single hand watches creating a more relaxed way of using time. The quest of making the most accurate timepiece made place for a minimalistic design which at first shows you an indication of the right time, but taking a closer look you can tell it to almost 2 minutes on the spot.


The Hourglass is actually the third design Rogier van Ree made, the first design, The Inkpot, was also a single-hand watch and now he wanted to take that concept a few steps further.

Inspired by watches with lots of glass, an idea crystalized in his mind to simplify time indication to its minimum: using a single rotating dial-hand with just a single mark to show the hours of the day. Much alike a sundial. Nothing else to distract the eye, not even the logo. And no part of the case to obscure line of sight.

That would be a watch for people who are really not in a hurry, no hard timeline to obey in any way. To make it interesting for a larger crowd, He decided to add a more accurate way of reading time. But how to without loosing that absolute minimalistic look of the dial-hand?
Having a single completely visible rotating dial-hand with hour markers on its side. This is a really unique feature of this watch. The glass is sapphire, of course.

For a quick glance at the pacing of the day you just take a look at the top. And when you need to know, you just twist your wrist to take a look at the side at 6 o’clock. You can estimate time down to about two minutes accurate using the quarter-hour markers and the little index on the case. A matter of practice you will master in no time.
The watch is another step forward towards the motto: time is essential but should not rule us to the second.

The case has an acceptable height to have it slide easily under the cuff of your shirt. The case is made of nickel free stainless steel. It measures 41m in diameter and is 12mm thick. Glass, case and bottom form a perfectly symmetrical shape.

The case is hardened to a degree that it is sheer unscratchable. Added up to the 2 sapphire glasses, your watch will keep looking great for years to come. The patented hardening process used is rather new to the watchmaking world.

Technical Features

A mechanical watch should have a see-through back to admire the movement and The Hourglass is no exception. The automatic movement is a Swiss made STP5-15 with custom rotor and is visible through a large sapphire glass.

  • Polished or brushed stainless steel case, 41mm in diameter, 12.0mm thick, 50mm lug-to-lug
  • Polished or brushed stainless steel back, screw-in, see-through and engraved
  • Nickel free stainless steel hardened to a sheer scratch resistant surface
  • Matte lacquered pastel colored dial in blue, rosé, green, yellow or sand
  • Sapphire glasses, box and bottom
  • Swiss mechanical movement: STP5-15 by Swiss Technology Production
  • French genuine goat leather strap, 22/20mm tapered, in several colors
  • Polished stainless steel folding buckle, 20mm
  • 5 bar water resistance


This watch is also made in a German workshop familiar with making jewellery to do the technical development and production of the custom made cases. And Swiss suppliers for the watch’s intestines.

The design of The Hourglass has been made shortly after the design of The Porthole. The Porthole was launched first, so most efforts went into prototyping that one. That was March/April this year.

However, in the same time they have been working on getting the parts of The Hourglass ready. So they were prepared when they started on the CNC machine in August right after the holidays. Most assignments for proto parts were given to the same Swiss companies who made the parts for The Porthole.

What was relevant to The Porthole is also relevant to The Hourglass: tolerances are nice but some of the design features require accuracy to the one hundredth of a millimeter. THey finished fine-tuning the case to the actual prototype parts Rogier received to meet those requirements.
