Customers praised the assembled timepieces for "excellent quality" and fast turnaround, with "very neat and high quality assembly." Most shoppers appreciated responsive customer service and detailed craftsmanship. However, some reported defective movements without adequate support, and concerns about bracelet limitations and dial sizing.
All was as expected from reading reviews. Very nice watch. Watch looks great and is assembled very well. Will buy from Adriel again in the future. Highly recommended.
Can not find any of these... it is very neat and high quality assembly!
I observed the watch thoroughly, the glass, casing, crown, bracelet, dials, hands, movement, setting process... all in a perfect and clean condition.
The plastic protection around and packaging are effective. Not a fancy box, but who bother on that.
I ordered a stainless steel case.
I like this watch very much.
The watch is really nice and fit perfectly to my wrist
I was very impressed by the quality of the bronze dial
Visibility of dial excellent, with dark too
Thanks to all of you
Watch delivered with the hands touching each other ; had to send it back and got little to no information in the meantime. But finaly that works fine, despite the case back is screwn in so tight that it blocks the winding mechanism.
This is my third purchase from LA and each time he delivers above and beyond. The watch was assembled and shipped to me within one week. Black case and dial with red hands, this thing is drawing so much attention it's amazing. The finish is perfect, no flaws at all. Add to that the hand written note from Adriel, always makes you happy to shop from him. Million percent recommended.
I am new to the hobby; after several months of research, came accross LA’s shop and was amazed by the offer. The timepiece was delivered in record time and it is amazing in quality. Thank you Adriel for your excellent service.
A l’écoute, réactif et très professionnel
This is the 2nd complete Tiffany dial Seikonaut I purchased from Lucius Atelier. Adriel is responsive (as always) and I received the watch more quickly than anticipated. Excellent quality.
Despite some parts being ok, you pay a lot, and you don't get much more for it. in my case the movement purchased in the store came defective, and no type of support or compensation was obtained
Help recieved was awesome and turn around was insanely fast.
I love the quality of the dial and the watch, I am very pleased with it, this is my second watch from them and I'll probably order more in the future :)
The watch is perfect, it was shipped really fast after ordering, thank you !
Adriel answered quickly my different questions and has provided a smooth and friendly support. Watch was assembled in a couple of hours and shipped the same day. I'm very happy with this experience.

Watch was assembled and shipped to me within one week !
Very happy with how the watch turns out. Customer service was amazing and will definately get more in the future
We were stunned by the luminous Starry Night dial for building a ladies watch in a 36 mm explorer case. New to modding my questions were professionally answered and included valuable advice. I did not dare to assemble myself and opted for a full assembly. I can Recommend Lucius Atelier for there honest and friendly advice, there outstanding parts and being very supportive in the whole project. The watch is so much more a live with a very detailed dial sparkling markers and GS hands that reflect the light or show the time on top of the lumed painting. So happy with the result, humbled by the craftmanship, service and personalized watch.

It's a unique timepiece with high a quality finish and I'm really happy to own a watch from Lucius Atelier!
I recently bought the custom Seikonaut case along with all the accompanying pieces and parts such as a dial, hands, and movement.
The watch case itself is built solid but the bracelet it comes with is the biggest issue. The bracelet cannot be swapped out for any other strap or bracelet which makes this bracelet the only one you can wear/use. In addition, when the butterfly clasp closes - it is not perfectly flush. Another issue I have with the bracelet is there is no micro adjustments because of the butterfly clasp and so when you remove the links, the bracelet either sits too tight on your wrist or too loose. It's hard to find a perfect middle ground.
The case only holds a 28.5 mm dial and I did not realize how small this dial looked in the watch. I should have done more research and asked more questions about this. However, in my opinion, the dial looks very tiny in such a large bezeled case. Looking at the pictures and looking at the watch in person are very different.
Hi! Does this service apply to the Seiko-Dweller 36mm Ultra Thin Titanium with NH38? Does it include rotor and bridge install? I'm a beginner and don't want to mess it up. Thanks!
Hi Chema,
Thank you for reaching out — and no need to worry, this service is a great choice for a first build, so you won't mess it up.
Yes on both counts: the Assemble Watch Case service applies to a 36mm Ultra Thin Titanium build with an NH38, and it includes rotor and bridge installation.
One thing worth knowing before you decide. The titanium case comes with a solid caseback, so even with the rotor and bridge installed, the movement won't be visible from the back. If you'd like to see the rotor in action, the alternative is to swap the solid titanium caseback for a 316L stainless steel sapphire caseback — that opens up the view. Just note this gives you a mixed-material build: a titanium case body with a stainless steel caseback.
Hope this helps. Please let me know if you have any other questions.
Best regards,
Adriel

Hello, is it possible for you to assemble the watch without a strap as I am looking to put my own strap on which I already have? Thanks!
Hi John,
Thank you for reaching out and expressing interest in our mod parts!
To answer your question: yes, of course! We can certainly assemble the watch for you without a strap. Straps and bracelets are completely optional when it comes to our watch assembly service, so we can easily build the watch head with or without them. You will be perfectly fine to just install the strap you already have once the assembled watch arrives.
Please let me know if you have any other questions or if you are ready to get your build started!
Best regards,
Adriel

Bonjour
Quelle différence entre le NH35 série M et série L ?
Cordialement
Gilbert
Hello Gilbert,
Thank you for your question!
The difference between NH35 Series M and Series L lies in the hand pinion height. This affects the clearance between the dial and the hands, which is important depending on your dial and hand combination.
For more technical details, you can refer to the official Seiko Time Module specification sheet here: www.timemodule.com/uploads/attachments/download/Spec%20Sheet/NH35_SS.pdf
If you have any other questions or need further guidance, just let me know – I’d be happy to assist!
Best regards,
Adriel

What is the difference between this model and the one named "Assemble Diver Watch Case"

These options are not available for purchases by itself. They are add on for customised watch parts that requires assembly.
