Love Watches?  Love All The Details? - This is the page for you!

When Daniel and Steve came up with the idea for SNGLRTY the focus was on developing the unique mechanical movement necessary to accurately display time with a single hand, it was christened OHI - One Hand Indication.  The moniker has stuck and OHI is used to identify the two movements; OHI4 for chronometer like accuracy and hidden complication and OHI2 for that clean look and functionality. 

The Collector's Choice - OHI4

  • Over 1000 Combinations: The unique construction of the SNGLRTY watch face allows for unparalleled customization & personalization
  • SELLITA SW300: Our exclusive OHI4 module is integrated into the slim highly engineered movement from Sellita in its fully decorated Premium Execution
  • Date Function: It may seem insignificant but the challenges of moving the date driver from the top of the movement to the top of the OHI4 module should not be underestimated
  • Our Signature Execution: Time keeping accuracy of +/- 4 seconds per day
  • Elegance & Security: The slim case construction is topped with a double domed sapphire crystal with anti-reflective coasting

Striking Simplicity - OHI2

  • Over 500 Combinations: The unique construction of the SNGLRTY watch face allows for unparalleled customization & personalization
  • SELLITA SW200: We have selected this reliable and robust movement to integrate with our exclusively engineered OHI2 module  
  • Swiss SuperLuminova: available in Grade X1, the highest available, as an option on every single one  of our watches in a variety of colors.
  • Exceptional Engineering: OHI module adds a  mere 1.5mm to the movement height.
  • Robust & Safe: the 10Atm water resistant case construction is topped with a sapphire crystal with anti-reflective coating 

OHI Module - Making Time Converge

The two movements, OHI2 and OHI4, share the same complication in the modification of the minute driver. The details of the module were developed by the esteemed watch movement engineers, Le Cercle des Horlogers SA who are based in La Chaux-de-Fonds in the beautiful Swiss Jura Mountains.

Crucially, the direction of travel of the minute driver is reversed and slowed to 11/12 ths of the classic rotation speed of the minute hand. 

The result is an elegant display that allows for time to reflect life, allowing opposing movements to converge and represent the time accurately - our metaphor for life, where nothing ever goes only in one direction.

Here we have speeded up time so you can see 10 minutes in 10 seconds, the minutes rotate anti-clockwise but remain in perfect alignment with the hour hand.

OHI4 - Dedication to the Details

Integrating the date function into the OHI4 movement may sound simple given how ubiquitous it is these days, but when the whole concept of the watch face has just been turned upside down by a new vision of time you need to go back to the drawing board to integrate each additional complication. 

The date driver on the face of the Sellita SW-300 had to be routed to the top of the integrated OHI module that delivers the unique SNGLRTY time display and ensures easy reading - as easy as a big date function.  The module for the OHI4 movement, composed of 18 individual elements, is 33.6mm in diameter and adds a mere 1.5mm of height to complete movement.

Stephen Mansfield & Daniel Blunschi
After struggling for years to come up with their new take on "time" Daniel & Steve worked tirelessly to bring it all to fruition, and after 3 years of research, prototypes lawyers and a number of set backs SNGLRTY was launched.  With a new look to time, we need a new way to buy it - you will never buy a watch like this again
