Naoya Hida & Co. NH Type 6A, NH Type 5A-1 & NH Type 3B-3

In 2025, Naoya Hida & Co. unveils the NH Type 6A, featuring a new caliber, Cal.3025PC, equipped with a perpetual calendar. The Roman numerals and calendar on the dial are all hand-engraved by skilled craftsmen. The hour and minute hands are made of 18-carat yellow gold, while the date, day, and month hands are made of blued steel.

Additionally, as a derivative model of the existing series, the NH TYPE 3B-3 features an 18-carat yellow gold case paired with a lapis lazuli moon phase disc.

The NH TYPE 5A-1, developed by changing the sapphire crystal of the NH TYPE 5A announced last year to an acrylic glass.

NH TYPE 3B-3

The NH TYPE 3B-3 is a derivative model of the NH TYPE 3B, which has been manufactured since 2022. It was created with the goal of condensing the details reminiscent of 17th-18th century pocket watches into the size of a wristwatch. 

The face of the moon, made of 18KYG (yellow gold), visible through the large cut-out window, and the eleven Roman numerals are all hand-engraved by skilled craftsmen. The most significant difference from the previous NH TYPE 3B is the change in the exterior from SUS904L (stainless steel) to 18KYG (yellow gold). Additionally, lapis lazuli is used for the moon phase disc.

• Production quantity: approx. 5 pieces to be produced between 2025 and 2026

• 18KYG (yellow gold) case, hands and crown

• Dial in German silver with hand-engraved Roman numerals

• Moon phase indicator at 6 o'clock

• Hand-engraved face on the moon in 18KYG

• Moon phase disc in the shape of the night sky made of lapis lazuli

NH TYPE 5A-1

The NH TYPE 5A-1 is a derivative model of the NH TYPE 5A, which has been manufactured since 2024. It was created as a dress watch with a small rectangular case. It features details reminiscent of vintage watches, such as a three-dimensional crystal, concave dolphin hands, and hand-engraved indices. 

The most significant difference from the previous NH TYPE 5A is the use of acrylic glass for the first time. This acrylic glass is newly manufactured using a custom mold. Additionally, Breguet Arabic numerals are used for the index at the 12 o'clock position.

• Production quantity: approx. 10 pieces to be produced between 2025 and 2026

• Acrylic glass manufactured using a new custom mold

• Two-part German silver dial with hand-engraved Breguet Arabic and triangular bar indexes
