Introducing the Ultra Thin Edition of the Explorer Watch Case, specially designed for NH Movements, boasting the slimmest profile possible!

With a mere 9.96mm thickness when utilizing a solid caseback, this 36mm watch case offers unparalleled sleekness and elegance. This is unprecedented given a NHxx movement is 7.59mm in thickness. Meaning that the sapphire, case and tolerance for hands add up to only 2.37mm!! It is thin, incredibly thin and without a doubt the thinnest watch case in the market for NH movement!!

Even with a sapphire caseback, the thickness is less than 11mm.

Included in the package are a flat double-sided coated clear AR sapphire, a choice between a solid or sapphire caseback, and a screw-down crown.

Crafted to accommodate all of our 28.5mm dials, SKX013 crowns, SKX013 chapter rings, and the original Type M NH movements.

When it comes to crown, 7mm offers a better grip over 6mm and knurled design has a better grip over coin edge. For the inquisitive, crown grip ranking: Knurled 7mm > Coin Edge 7mm > Knurled 6mm > Coin Edge 6mm. 7mm crowns will also look slimmer than 6mm even though they are the same thickness - an optical illusion similar to Müller-Lyer Illusions.

Choose your preferred bracelet from the dropdown list above or explore the options in the bracelet category .

The water resistance of this watch case reaches 50m, ensuring durability alongside its impressive design.

IMPORTANT: This case can ONLY fit TYPE M of NH35, NH36, NH38, NH70, NH71 and NH72 movement. TYPE L of these movements will NOT fit. Due to low tolerance/space between hands and sapphire, this case is ONLY recommended for professional watchmakers and highly skilled/experienced modders with great level of finesse.

Ultra Thin Expplorer case.

Beautiful case, with a hi quality look and feel. Don't be put off by the "highly skilled/experienced modders" disclaimer - this was my second mod, and everything went together well. Paired here with a Namoki dial and hands, I'm very happy with the result.

The best explorer case

I have purchased a few different explorer cases from the usual seiko mod part sellers, this is by far the best. This case is well made, slim and stands apart from other cases with the way that it sit on the wrist. Buy it with the bracelet,

Love my Ultra Thin !

I have an NH35M installed in my UT case. In this creation, I also used a Raffles Space Dweller dial, with lumed gold hands, Oyster bracelet. Looks great, and wears very nicely.

I also have two more similar builds, one with the LA blue tapestry dial, and another with the LA meteorite dial.

Super cool watches thanks to LA.
All high quality parts, and excellent customer service.

Thanks LuciusAtelier !

Fantastic thin case

This is thinner than I thought possible with NH movement--mine is 10.9mm with a display casebook! Allowed me to build the perfect mid-century retro-watch.

Excellent Low Profile Case

Bought for a fully custom watch build, looking for smaller diameter and lower profile. It was fabulous experience to build with and the knurled crown feels great in use.

Keeping on my list for future builds.

Stunning well built case

Purchased this case for a build to replace an inferior explorer style case purchased at another supplier and this is simply leaps and bounds better quality. great machining, excellent fit, and SO SLIM. build went together great and I'm so happy with my purchase. The large knurled crown is particularly nice.

Best 36mm explorer case

10mm thickness compared to 12 - 13 mm thickness is a very noticeable difference, especially for smaller 36mm watches. This is a really nice and well finished case.

The ultimate 36mm explorer case

What an amazing case ! The best balance between thickness and case size. Perfect fit on my wrist. The crown with Seiko S is really nice too.
