The three leaf hands machined by an ultra-high precision micromachine are polished by hand and turned into blue steel by applying heat. When incorporating the hour hand into the watch, the tip is manually bent to fit the minute scale around the dial.

Exterior parts, such as cases and crowns, are machined using ultra-high-precision micromachining machines at the world’s highest level to cut this hard-to-work stainless steel with an accuracy of several microns. This reproduces the complex shapes such as the concave bezel and curved lugs often found on vintage watches.

All Breguet Arabic indexes on the dial are hand-carved by skilled craftsmen. After that, the lacquer (cashew) is poured to create a three-dimensional finish.
The NAOYA HIDA & Co. TOKYO brand logo is engraved with an ultra-high-precision micromachining machine, and is filled with synthetic lacquer (cashew) as well as an index.

Made from 904L stainless steel, which is known to be used only by very limited brands due to its high corrosion resistance but difficult to cutting by machine.

The 16mm wide vintage style pin buckle is also polished after cutting 904L stainless steel with an ultra-high precision micromachining machine. The shape of the pin is composed of rich curves. The leather strap is hand-sewn, the surface is made of vegetable tanning calf and the back is made of rubber to prevent perspiration.
