One Hand Indication. When Daniel and Steve were developing the watch they did not have a name for it so they called it One Hand Indication. It was only after they received the patent was the name SNGLRTY created.
Provided that all the components are in stock (and they should be if you have chosen from our stock list), your watch will be delivered within 4 weeks. If you have a customised component then we will advise you on the expected delivery date as soon as the final configuration is confirmed.
If you receive your watch and you decide it is not for you please just return it to us in the same condition as you received it within 30 days and we will give you a 100% refund. No questions asked. We believe that SNGLRTY is not just a watch, but reflects how our customers want to #seetimedifferently and if it is not for you we completely understand.
Like every mechanical watch it will require servicing every 4 ~ 5 years. This is no more than recommended by any other watch – the fact we display the time differently does not alter the way the basics of the watch works.
What is really cool about SNGLRTY is that if you send your watch back to us for the servicing you will get the option to reconfigure your watch face with different colors at that time (for an additional small fee).
We are happy to reconfigure your watch face at any time, all you need to do is contact us and we will make the arrangements with you. If you become a SNGLRTY owner you will also have the opportunity to join our special care program where you will have the opportunity to reconfigure your watch every 4 years when you send it for its service.

Hour Numerals Color

I like to think the color of the hour numerals creates the personality of your SNGLRTY watch. We have the basics, black and white, but if you would like to have your watch glow in the dark we offer a range of colors in Swiss Super-LumiNova. We always use Grade X1 for the best luminous effect but the daytime colors do impact the ultimate performance of the Super-LumiNova. If you want the brightest possible luminous effect choose Swiss Super-Luminova White, and if you want more please contact us.

Color Of The Hour Ring

The hour ring is the largest surface area on the SNGLRTY watch face so sets the tone for the rest of your design.

Date Display

Each of our watches can be configured with a date display, or without. Due to the mechanics this is the first decision you need to make in your journey to create your SNGLRTY watch.

Comparison Ohi2 vs. Ohi4

The OHI movements, or One Hand Indication, are unique to SNGLRTY. During the development phase of the watches Daniel and Steve used this moniker before naming it SNGLRTY. There are two distinctive movements to choose from, OHI-2 and OHI-4.

The OHI-4 movement is built on the Decorated and Fully Adjusted SW-300 tractor movement from Sellita. On top of the tractor movement the SNGLRTY complication plate is assembled and incorporates the “reverse minute gearbox” that is available exclusively from SNGLRTY. Depending on your selection, the complication plate will also relocate the date wheel from the top of the tractor movement to the top of the complication plate. Relocating it in this manner increases the size of the date disc and moves it closer to the top of the watch face improving its readability considerably.
The OHI-2 movement is the same as the OHI-4 movement except that it is built on a standard execution Sellita SW-200 movement.

Finally, depending on the movement you select the watch case will have a different profile as the OHI-4 movement is thinner than the OHI-2 movement. The key differences are that the case for the OHI-4 movement has a double domed crystal and a flat caseback. The OHI-2 case has a flat crystal and a curved caseback.
