The Patented Single-Hand Watch By Crystal Clear Watchmaking

patented single-hand watch with crystal clear watchmaking title cardDaniel and I were honored to be invited on to the 40th episode of the Crystal Clear Watchmaking podcast to discuss SNGLRTY – The Patented Single-Hand Watch. Luc Robitaille took us on a broad discussion on watches, microbrands, crowdfunding, and SNGLRTY, to name but a few of the subjects we covered.

This is nothing to be surprised at, as Crystal Clear Watchmaking is not afraid to take on some prickly subjects in watchmaking. Luc and his cohost Jay discuss watches, brands, gears, springs, and oils – all things watches and watchmaking! If you’d like to learn about watches inside and out, this is the podcast for you! This was a conversation that Daniel and I thoroughly enjoyed.  

Here is Part One of the conversation, edited to make it easier to read.  If you would like to listen to the whole podcast, you can listen below or find it on your favorite podcast provider.


Welcome to the 40th episode of the Crystal Clear Watchmaking podcast. I’m your host, Luc, and I am here today with two very special guests. Would you like to introduce yourself?


My name is Steve Mansfield; I am one of the co-founders of SNGLRTY watch. Hi


Hi! This is Daniel Blunschi out of Switzerland. I am the second co-founder of SNGLRTY watch.


Now, these guys got in contact with me on Instagram. Everyone can get in touch with me there. And I have to say, you guys are the first people to make me laugh with your first message to me. You wrote we had created a new watch brand. Sorry!


Well, You have got to be truthful about these things. There are a lot of watch brands out there.


Perhaps too many.

Patented Single-Hand Watch


There are. The thing is, it is kind of funny because I could imagine being annoyed by some of these Alibaba watch resellers doing the U.S. fashion watch thing. I could see myself being annoyed with that. You guys, though, are making a brand with a new complication. There is no way I would not want to talk to you. So you do not need to be sorry. You should be proud of yourselves!


Well, I liked the edginess of your podcast, so I thought I should match you with a little bit of edginess with our introduction. But we are very honored that you recognize what we are trying to do here and, bring a little bit of something new and innovative to the watch business.


Yes, it is awesome. Now I have had a number of listeners say that we should describe the watches we discuss. So I will take a second and describe the watch, so hopefully, everyone can imagine it.

Patented Single-Hand Watch – Circular Case With Slightly Curved, Slightly Fancy Lugs

You guys are called SNGLRTY watches. So if you take the singularity of a black hole and then delete all of the vowels, that is how you search it on Google. This is what it looks like; it has a circular case with slightly curved, slightly fancy lugs. The hours on the outside and then it has a counter-clockwise running minute track on the inside. That is like a date wheel, but it runs counter-clockwise, and it rotates once every hour. Thus, there is only a single hand and it points to both the hours and the minutes simultaneously.  This is achieved because the minutes are moving through the center of the hour hand. Then in the center, there is a small sub-second style seconds counter. That is it. It is a single-hand way of seeing the hours and the minutes at the same time. 

When I was thinking about it, my first thought was that the minute track moves 360 degrees every hour, or it moves 60 minutes of distance, but that is not true.


That’s right.


It moves 55 minutes of distance in one hour because the hour hand is moving the other five minutes. Right?


Yes. You have got it.


So you guys have a unique gear ratio to accomplish that, which I appreciate.


If we take a step back, the whole idea came from the display of time. Daniel and I had been working together on another watch project. Part of that challenge was we were trying to come up with something new and innovative. We were looking to do a watch. Something kept holding us back from doing it.  Each idea we had was just a variation on a theme, and we saw a vast number of watch brands out there like that. 

As all good stories seem to have a bar and a bottle of wine in it somewhere, we were in a bar with maybe too many bottles of wine one night. We were talking about watches; now, my background is not in watches. I have come up the learning curve quite quickly over the last few years. I studied engineering at university and I do like the mechanical aspects of watches and really anything mechanical. 

Watches And Cars – Inextricably Linked!

In the bar that evening, Daniel talked me through the watch movement; it became apparent that it breaks down into key units. It is a beautiful micro mechanical solution to keeping time, but it is very similar to a car propulsion system. You have a power source, an engine, and then a gearbox. That is pretty much how a watch breaks down too. 

We had zeroed in on that gearbox, and in my mind, I had a sudden thought. I have no idea why this came to my head at the time.  That thought was what would happen if we put a reverse gear in a watch? What could be sent backward that could make some sense?

The Propulsion Systems For Watches and Cars Have The Same Basic Functional Units.  Power Source, Engine, and Gear Box.

That was the genesis of SNGLRTY. I suddenly realized that if the minutes move backward, we can accurately display the time at a single point on the watch face. 

We wanted to try and create something new for the best part of perhaps eighteen months or more.  The ideas had been bouncing back and forth for quite some time. When it came down to it, the idea of how we presented time was the catalyst that resulted in SNGLRTY.


Steve was looking to align the time. He was looking at an almost digital way to show time, aligned on one plane – but with an analog movement. At the time I said that it was a bit of a challenge to achieve that.  Finally, we managed to achieve it by displaying the minutes in the opening of the hour hand as the hour hand indicates the hour. 

The result is that we were able to make a patented single-hand watch that indicates the minutes precisely. It is not up to you to guess the exact minute; the exact minute is displayed with the same hand, the hour hand. It aligns time.


Some people think that really great ideas need to be complicated. This one, when you really think about how it is done, it is so simple, but it is also so genius. That is how really good things are made. Very simplistic changes that are profound – if that makes sense?

Simple Does Not Mean Easy


Yes, I absolutely agree with you. You know, it is so simple on the one hand that people always think, “Yeah, I have seen that already.” That was also my first reaction. I thought someone must have done this already. Then we checked. We really checked. I went to a movement manufacturers. I went to engineers here in Switzerland. They all said the same thing initially, that has been done.  Most of them believed that Breguet first did it. 

Then they would look through some books for an example. Eventually, they would return to admit, no, actually it has not been done.  The SNGLRTY movement was different from what they were thinking of. We were not able to find anything the same. 

There are a lot of single-handed watches out there.  The issue is that the minutes are always a guess because each minute is indicated in a twelfth of the space. To put it another way, you have to read 60 minutes in 15 degrees, which is not easy. 

There are also disc watches where the hours and the minutes are indicated on the disc. Here there is no rotation or no hand rotating. The time is consistently aligned at a single point, perhaps at three o’clock.  This makes reading the time more complicated. 

We wanted to keep a key recognizable element of the classic watch – the hour hand. When I look at my watch, the hour hand is approximatively the time. For example, I can see it is a little bit after five o’clock here in Switzerland. With the SNGLRTY hand, you can then see the minute.

That is what makes it different. It is simple, but not easy to do.


As I like to say, simple does not necessarily equal easy. 

When we got over our hangovers the next day, and started to really talk. We realized that we potentially had something. But that road from idea to prototype was challenging to say the least. Along that road, we also received a patent for the display.

In Part Two of this serialization of the Crystal Clear Watchmakers Podcast Luc is delving into the patent application process with Daniel and myself.  Then Daniel takes us on a journey through his early education in the watchmaking world.  We find out how important a tenth of a millimeter is in a watch design and discuss bandwidths.

We are so confident that you will enjoy Seeing Time Differently every single watch comes with our Money Back Guarantee so you can buy with confidence. If you have any concerns after your purchase, just let us know within 30 days of delivery and we will refund your money. After all, Daniel and Steve want everyone to enjoy wearing SNGLRTY on their wrist.

Free International Shipping

UPS will whisk your beautiful new SNGLRTY watch from Bern, Switzerland to your front door – and you will be able to track it every step of the way and reduce your waiting to the minimum.

2 Year International Warranty

Where ever you are, if there is a problem with your watch (and we seriously doubt there will be), we will make sure it is put right so you can buy your SNGLRTY watch without any worries, wherever you live.

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.
