Salmon GS!!!

I absolutely love this case. The brushing is the best I’ve seen on seiko custom case. The bracelet on the other hand, you can tell attention to detail was missed here. All on the end links. I understand why though, to save cost and for the universality Between LA cases. But even though all this, the bracelet some how allows the case to showcase its dimensions. This has become my favorite custom Watch. @alonsinni

Awesome Case

Bought this case along with a lapis lazuli open heart dial and dauphine hands. Had to have this case soon as I saw them announced, and the style and build quality are wonderful. Lots of character compared to all of the explorer style 36mm cases out there. Highly recommend!

Wonderful case!

The case is gorgeous and the 36mm size is super wearable. Very well done to the team at Lucius Atelier

Could’ve been perfect

Finishing is nice but like the other 36mm case I feel like the proportions a bit out of whack with the thickness. It’s more than 13mm with the slightly domed crystal. I think the NH movements may be causing this difficult choice of not having the dial closer to the crystal as it feels a bit too deep currently but with tighter tolerances I think this could’ve help shelved some mm off the midcase area. Also the lug holes for the strap is so close to the edge making it accentuate the thickness of the case even more. But still I appreciate the effort in making this case!

Perfect!

As other reviewers have mentioned, the finishing on this case is truly exquisite! The brushed bezel captures the light in an incredible way, lovely design. Slightly domed crystal is nice, and dimensions are perfect for my small wrist. The oyster bracelet doesn't sit flush with the lugs, and is clearly not made to fit this case perfectly, which annoyed me a bit at first, but it's a very small blemish in an overall exceptional package. Great buy, but skip the bracelet if what I mentioned would bother you (regardless bracelet feels great and is high quality)

4.5/5 - Surprisingly nice finishing

This case is great, the finishing is surprisingly nice for the price. The brushed sides are super clean and smooth. Only thing I would like done better is the thickness... it is a little chunky.

Girlfriend's Watch

Long story, but she is estranged because of Covid and I promised her a custom watch like my own SKX013. Majority components purchased, she vetoed the dive watch concept and 39mm size, so I have 2 trick SKX mods. ;-)) Such a shame.
When L.A. announced the first 36mm GS design, I jumped at it.
I'm likely one of the first in Europe to handle one and I am absolutely Delighted.

Best aftermarket case out there

THe quality of this case is amazing. Not a single sharp edge in sight and the finish is amazing. A great backbone for any elegant build

Grail Watch Build

I purchased the 36mm GS Watch Case to build up an homage to my grail watch, the Seiko SLGH005. I purchased the Shirakaba dial, lumed dauphine hand set. I chose the plain case back and O-style bracelet. I'm extremely pleased with the result. Thank you Adriel!!!
