    Introducing the Pilot Watch Case Ultra Thin Edition—crafted for NH Movements, it is the epitome of refined minimalism with a compact yet robust design that speaks to aviation-inspired aesthetics.

    Despite modern trends toward larger watches, smaller cases—like this Pilot Case 34mm UTE—offer a distinct charm. Their size provides an understated elegance, ensuring the watch complements rather than dominates your look. Small watches also evoke a timeless appeal, drawing from decades of classic design that never goes out of style. Perfect for any wrist size, they balance subtlety with sophistication, making them versatile for both formal and casual wear. The compact design emphasizes craftsmanship and proportion, highlighting the beauty of simplicity.

    Building on the slim profile of the Explorer Case 36mm Ultra Thin Edition, this Pilot Watch Case 34mm gains an additional 1mm in height due to the inclusion of a double domed sapphire crystal. Thus, enabling this case to accommodate the GMT NH34 movement, making it the smallest and thinnest GMT case available for this movement.

    With a mere 10.96mm thickness when utilizing a solid caseback, this 34mm watch case offers unparalleled sleekness and elegance. This is unprecedented considering a NHxx movement is 7.59mm in thickness. Meaning that the sapphire, case and tolerance for hands add up to only 3.37mm!! It is thin, incredibly thin.

    Even with a sapphire caseback, the thickness is less than 12mm.

    Included in the package are a double domed and double-sided coated clear AR sapphire and a choice between a solid or sapphire caseback.

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

    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 NH34, 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. For optimal second hand clearance of NH34 movement, second hand must be at a length of less than 12mm; alternatively a second hand cap.

    Visually beautiful high quality case

    I used the Pilot Watch Case - 34mm ultra thin edition to build a Venturine dial watch for my wife. The case is visually beautiful and all its parts are of very good quality.

    Not Just Made—Masterfully Crafted

    As this was my first build, I had numerous questions, and Adriel was very accommodating to answer my questions. I went with this 34mm UTE Pilot Watch Case to accomplish a vintage-like look. I paired this case with the Brushed Silver Chapter Ring and the 6mm Coin Edge Crown. Every piece I purchased from Lucuis Atelier reflects flawless craftsmanship and impeccable quality. I was pleasantly surprised to find that the case fit the 39mm dial I selected for this build flawlessly. The movement is a Seiko NH35A. For reference, my wrist is 6.25”. In the end, this case brought the entire build together beautifully—flawless fit, premium feel, and undeniable craftsmanship.

    First Build! Super happy! 34mm UTE

    I chose the 34mm UTE and the snowflake dial as my first build for my fiance as a travel gift. I couldnt be happier with the quality and fit of the parts, the packaging, and the communication. She has a 6" wrist for reference in the pictures.

    Forstner Klip bracelet and a quick release grey leather. UTE polished chapter ring, lume GS style hands with blue second hand, NH38 movement, and 7mm diamond crown. Adriel was great helping me select parts when I had questions. Took my time and was very careful with the minute markers.

    Truly Stunning!

    Adriel was very helpful answering all my questions - this was my first custom watch build and I had several. I was intreguied by the capability of having a automatic GTM watch in a slim case - and it turned out truly stunning! This started by selecting the snowflake dial, and grew from there. The subtle details are a joy to observe - the textures, colours, and robust feel of the compact package. I am very happy with this purchase.
