What’s actually slowing this PC down?

The Naoya Hida & Co. NH Type 6A is the Japanese watchmaker’s first perpetual-calendar watch, introduced in May 2025. Its hand-wound Cal. 3025PC displays the date, day, month and leap year, while a 37 mm steel case frames an Argentium silver dial engraved by Keisuke Kano. The 2026 listing price is JPY 8,800,000 including tax, but the brand says its 2026 production is sold out; applications for the next production period are scheduled for May 2027, with availability not guaranteed.
What the NH Type 6A does
The Type 6A brings a perpetual calendar to Naoya Hida & Co.’s restrained, vintage-influenced dress-watch style. Its calendar shows four indications: date, day of the week, month and leap year. The brand’s first watch with this complication was introduced in 2025, with the model’s launch date listed as May 2025 by the Grand Prix d’Horlogerie de Genève (GPHG).
A perpetual calendar is designed to account for the differing lengths of months and leap years without routine manual correction, unlike a simpler calendar that requires adjustment after short months. The available specifications establish the Type 6A’s indications, but do not detail its operating limits or correction procedure. Owners should follow the supplied instructions when setting the calendar.
Cal. 3025PC: a collaborative hand-wound movement
The Type 6A is powered by Cal. 3025PC, a manually wound movement developed with Habring2 and Dubois-Dépraz. GPHG describes the architecture as a Dubois-Dépraz perpetual-calendar module combined with components from Habring2’s A11B base movement and proprietary parts from Naoya Hida & Co., including bridges, click springs and screws. This makes the watch a collaboration rather than a wholly in-house calendar mechanism.

| Cal. 3025PC specification | Value |
|---|---|
| Winding | Hand-wound |
| Diameter | 30 mm |
| Thickness | 7.3 mm |
| Jewels | 19 |
| Frequency | 28,800 vibrations per hour (4 Hz) |
| Power reserve | Approximately 45 hours |
These movement figures are from the maker’s 2026 product listing. GPHG independently lists a 45-hour reserve and 28,800 vibrations per hour.
Engraving and materials define the dial
The dial is made of Argentium silver, which the maker describes as resistant to tarnishing. Engraver Keisuke Kano hand-engraves its Roman numerals and calendar sub-dials. The maker says black artificial lacquer is applied to the engraved numerals; GPHG notes how the engraving and lacquer give the dial a three-dimensional character.

The hour and minute hands are 18K yellow gold, machined and hand-polished. The calendar hands are heat-blued steel. The result is a display with several indications, but one that uses engraved registers and differentiated hand materials rather than adding a busier visual language.
Case, water resistance and strap
| Specification | NH Type 6A |
|---|---|
| Case material | Stainless steel |
| Diameter | 37.0 mm |
| Thickness | 11.5 mm |
| Lug-to-lug | 44.5 mm |
| Water resistance | 5 bar (50 m) |
| Lug width | 20 mm |
| Warranty | Two years |
The 5-bar rating appears on the brand’s 2026 listing; GPHG gives the equivalent 50 m figure. That rating is a specification, not a claim that the dress watch is intended for diving. The included hand-stitched leather strap is attributed to THE SOLE and uses ILCEA Radica Russian leather on the surface and Perlinger Noblesse calf leather underneath. The 20 mm lug width can help when considering a replacement, but does not by itself establish fit for any particular aftermarket strap.

Price and planned production
Naoya Hida & Co.’s 2026 listing gives a price of JPY 8,800,000 including tax, or JPY 8,000,000 before tax. The official site lists prices in yen and asks readers to convert to local currency, so the yen price is the clearest current reference rather than a fixed equivalent in another currency. The same listing describes production of approximately 10 pieces across 2026 and 2027; this is a plan, not a confirmed count of completed watches.
Hodinkee reported a USD 57,300 price and application lotteries through the brand’s website and The Armoury at the 2025 launch. Those details describe the launch period, not current pricing or a current application route.
