Naughty

A remodelled mod. Iteration 3 of this gorgeous case finally sticks! Adriel helped me out after I ruined the crown spring, and continues to be a stand up member of the modding community. Thanks again!

This case is awesome

This case and band are super high quality, I did a custom build with open heart birch dial and nh38 movement. I the first hands I used I didn't like so I switched them to a easier to read sportier hand. I uploaded pics of both.
Fast delivery. Very comfortable to wear. It is a very classy look. I will probably buy another of these cases and do a second mod.
I have purchased multiple movements here now and they are much better then the ones I had been buying at Crystal Times, every one from LA has been 6s or less. The CT regulated have been around 25s which is not acceptable. I just dial them in further on my time Grapher. I have been able to get the ones from LA dialed in to 1 or 2s.
Great service, everything I have ordered has been top notch.

Wow…just wow

Having bought from LA before, I knew I’d be getting a quality product but this has far surpassed my expectations. The build quality and finishing are top notch and it wears SO well. This may just be my #1 watch of the summer!

I like it!

I was suprised by the quality of polishing and details. What's more important the seikonaut by luciusatelier is not a PP ripoff or how you say "homage" but completely new design inspired by - which makes this watch interesting :)

Incredible quality and value!

The quality of the design, fit and finish are impeccable. The bracelet integrates perfectly with the case. Couldn't be happier with this build!

Amazing

It’s my second case I get from here and the quality is amazing, I got the hands and the dial also( one of the most beautiful that I’ve seen). The only thing I could say about it is that I think it should have come with half links in the bracelet for a better and nicer adjustment for all sizes of wrist. Other than that this is amazing.

High quality, comfortable to wear

Great case for my SARY147 mod. Integrated bracelet is very comfortable. The polishing and brushing are immaculate.

My precious Seikonaut

First, this case is beautiful by itself and perfectly done. Very easy to build, every part is machined well and fit together without the need for any adjustments from me.
Now, let's talk about the service. I pre-ordered the case and misread the estimated delivery date (my fault), so when the case was ready to ship, I was out of my country for a long time. I just send an email asking to keep my order till I came back and very quickly got an answer from Adriel telling there was no problem. I just send a mail when I came back (more than a month later) and the package was send the same day !
To conclude I'll say that this was perfect from start to end ! Product quality, service and quick shipping !
