Series 4

Designed and made on the Isle of Man

“I had wanted to create an instantaneous triple-calendar wristwatch for some time, but was initially dissuaded by the often difficult-to-read dials.”

“To accommodate this complication, the Series 4 is a slightly larger 41mm cased, manually wound wristwatch displaying hours, minutes, seconds with date, day, month and phase-of-moon complications.”

Series 4

Roger’s personal remarks

“The Series 4 represents my ultimate challenge and is, in many respects my ultimate watch. It is certainly the most complicated, but that wasn’t really the challenge.

Something George Daniels drummed into me as a young man were his ultimate principles of watch design - clarity and simplicity. George absolutely hated watches which looked like an Enigma machine, and needed an Alan Turing to work out the time! As we curate a new British watchmaking tradition, I believe that elegant simplicity must be our design creed.

So, with the Series 4, the complexity wasn’t really the quest. Anyone can create a carbuncle! The real challenge was achieving this complexity whilst concealing it within a deceptively simply aesthetic - and preserving the primary purpose of a watch - to tell the time in an instant.

The function which has always stumped watchmakers is the travelling date-hand, since this travels and sits over key date information for several days at a time thus compromising the dial’s legibility.

After several years of drawings and experimentation I came up with my new Travelling Aperture, which I believe is the first time this complication has been created. It simply reverses the function, by having the Travelling Aperture orbit the outer edge of the dial, thus removing the need for that problematic hand!”
