Known Models	Liudas Norkus LN1 Regulator (Add your watch to the comments below…)

The Liudas Norkus caliber LN1 is a manual-wind movement found in the indie watchmaker’s debut model: LN1 Regulator. After almost 3 years of development, the LN1 was introduced on Instagram and LinkedIn in January 2025 – the same month the brand was registered as a company.

In Liudas Norkus’s own words:

“The watch features a three-dimensional dial inspired by pocket watches, with Roman numerals and visible brass components like pillars, a barrel, and bridges. It has an in-house modified ST3600 manual movement, with separate hands a hours, minutes, and seconds displayed on two sub-dials and a chapter ring. A visible winding barrel with a transparent spring is located at 5 o’clock, held in place by a bridge, all visible parts of the watch are hand finished and gold plated in 24k.” –Source

As of this post, pictures of Liudas Norkus showing the movement from the back could not be found. It appears that the LN1 Regulator watch has a solid caseback. Caliber Corner has reached out to Liudas Norkus and will request additional images. This post will be updated accordingly, so please check back.

Update: from this video on YouTube showing the movement under the hood, it looks like a stock ST3600 from that side – which could explain the lack of images or exhibition back. To be fair, all of the action with this piece is on the dial side. Still, a refinished mainplate and view to the back could have taken the piece to another level (but sometimes you have to know where to draw the line for production to make sense).

Base Caliber:

The LN1 is powered by a modified Seagull caliber ST3600 (ETA 6497 clone).

At least one instance of the brand’s use of “in-house” may raise some eyebrows by fast readers…

“I am working on my upcoming first series Regulator watch, completely designed in house, a project I have been developing since 2022.” –Source

But notice that the quote states that the watch is designed in-house. Later posts by the brand more accurately describe the movement as being in-house modified (see quote above).

Design and Custom Modifications:

It is cool to see what the brand accomplished with their first piece – and the modifications they made to a Seagull movement as the base. Perhaps you could call it a poor man’s Auffret Paris, but that’s a vibe that many would gladly be put on a waiting list for.

Hands:

The 24K gold plated hands were designed in CAD, then hand-finished after being laser cut out of brass.

Top Plate (Dial):

The top plate, that serves as the dial, was made with a lathe and milling machine. It is then finished by hand and sandblasted.

Dial Bridge:

A 24K plated dial bridge holds the offset hours subdial which measures 15.5mm in diameter.

Cannon Pinion Bridge:

This is an interesting component – a small cannon pinion bridge made to keep the extended cannon pinion vertically aligned to hold the regulator-style central minutes hand.

Chapter Ring:

The custom chapter ring is held in place by four handmade pillars and mirror finished screws.

Barrel Bridge:

24K gold plating adorns the barrel bridge that holds the barrel from the dial side with four pins and two mirror finished screws.

Barrel:

The mainspring barrel is laser cut with a skeletonized design and finished with a circular brushed pattern.

Country of Origin:

Based on images shared by Liudas Norkus, the LN1 Regulator does not have any country of origin markings.

The base calibre is made by Seagull in China and modified heavily by the Lithuanian watchmaker in England (UK).

Caliber Number:

Technically, it is not called the calibre “LN1” (at least as far as we know). The watch is called the LN1 Regulator, with the “LN” being initials for Liudas Norkus and “1” being the first piece the brand released.

Since no caliber designation has been applied to the inner workings of the LN1 Regulator watch, Caliber Corner is going with LN1 as an identifier.

Sometimes, indie watchmakers are so consumed with their creations that they overlook other important aspects of marketing and communication such as consistent social media posting and caliber numbering. Minhoon Yoo is another example of a talented indie brand that has not named the movement in his first piece.

Sold Out:

It has been reported that Liudas Norkus sold 200 pieces of the LN1 Regulator in less than 24 hours (maybe 2 hours?).

Pre-orders were taken via an invite-only WhatsApp group (see Liudas Norkus Watches on WA).

Originally there were going to be 300 pieces, but the number was reduced to 200 before the pre-sale.

The price for the LN1 is in the £900 range, which exchanges roughly to $1,200 USD.

Liudas Norkus’s Official Site:

Surprised that Liudas Norkus did not list a website on the brand’s social media accounts, Caliber Corner decided to check LiudasNorkus.com in an effort to uncover any additional information about the movement in the LN1.

Shockingly, LiudasNorkus.com was automatically redirected to Vaucher Manufacture Fleurier’s homepage! Is Liudas Norkus playing a joke on us by creating a URL redirect to Vaucher? Or, did Vaucher buy the independent watchmaker’s URL? It remains a mystery for now.

Update: Please disregard what you just read above, because now the site is going to a blank page. Was it a fluke? Did I mistakenly click something else? Not sure! Having I been working too long finishing this article at 1AM? Maybe!

Caliber Commentary:

You will likely come across critical comments online pointing out that it is a Seagull base and not worth the asking price because of that – and of course there are pros and cons to using a Seagull as the base, but do yourself a favor and look past the bias against Seagull and realize that whether Seagull or ETA, the modifications are enough to cast a shadow on the base. Sure, with an ETA you can source parts if needed in the future, but there are so many ST3600 movements produced, and at such a low price, you should have no issues with purchasing an entire movement and taking the parts you need from it. As for the modified parts, you won’t be able to get those no matter what the base is. The ST3600 is by no means a bad movement, quite the contrary, especially when it is  oiled and regulated correctly.

This is just an opinion (like 90% of anything else in watches – although who would admit it), but for the design and amount of work going into these pieces, the price is a bargain and probably not earning much profit for the brand. Think of it as a give-and-take experiment to help Liudas Norkus prove the concept. On the plus side, this is great for building awareness and putting the brand on the map. But I’ve seen it far too often where a low entry price sets an unrealistic and unfair bar that the community expects from everything the brand produces going forward. It is a really tricky game to play! If you’re considering starting a new brand that requires a tremendous amount of work from machining to assembly, keep in mind that while pricing low gives more people a chance to own a piece of your creation, it also unfortunately attracts a negative type of customer who won’t want to let you grow beyond their price-range in the future – your watches will forevermore be not worth it in their eyes. Pricing too low can also lead to burnout and not feeling like you’re being compensated fairly for your effort, especially when you see other successful brands selling out of hundreds of pieces they ordered from a factory. It’s definitely a chicken-or-the-egg, cart-before-or-after-the-horse type of situation to be in. But ultimately, what you have to do in any situation in the watch industry, is learn to block out the haters and cynics – and remember that most of them weren’t going to buy your watch in the first place. Take it as simply an observation – not necessarily advice – from someone who has been working with brands (as well as working on brands) and selling luxury watches online for almost 17 years.

With that said, I do find it interesting that some of these brands sell-out with minimal effort in social media and barely replying to comments. It’s definitely a new world where the brands lay the tracks and the community builds and fuels the train.
