SEIKOAK Frosted Skeleton

The SEIKOAK Frosted Skeleton draws on one of the most iconic silhouettes in luxury sports watchmaking: an octagonal case with exposed screws, a skeleton dial revealing the movement's gears, and an integrated bracelet. Its unique frosted finish on the stainless steel case and bracelet gives it a distinctive texture and sparkle.

Hand-assembled in France around an authentic Seiko NH70 automatic movement, this timepiece combines elegant design with reliable modern performance. Every watch is regulated and tested with the utmost care before shipping.

Technical specifications:

• Movement: Seiko NH70 automatic
• Case: 316L stainless steel, 41mm diameter
• Crystal: Scratch-resistant sapphire
• Caseback: Transparent
• Bracelet: Integrated stainless steel with frosted finish
• Case thickness: 12mm
• Water resistance: splash-resistant (everyday wear) — upgraded option 5 ATM available

Customize it your way — dial color, bezel, bracelet, logo or engraved image. Create your custom SEIKOAK with our configurator or by describing the changes you'd like in the order note (before completing checkout).

Comes with a storage box and sizing kit. 2-year warranty against manufacturing defects. Free tracked shipping — delivered in 10-14 days.

A custom Time2Seiko creation — not affiliated with the Seiko brand.

All our watches handle splashes, rain and hand washing. That's enough for normal everyday use.

At checkout, you can enhance that water resistance:

• 5 ATM (50 m) — shower, washing up, heavy rain. Not for swimming.

• 10 ATM (100 m) — pool, sea, snorkelling: you can swim. Not for scuba diving. Available on SEIKOJUST, SEIKODATE, SEIKOMARINER and SEIKO GMT.

ATM stands for atmosphere: 1 ATM is the pressure of a 10-metre column of water, measured in laboratory conditions. These figures shouldn't be taken literally, as moving your arm through water generates far higher pressure. Our usage recommendations are therefore deliberately more cautious than the numbers suggest.

Important: the crown must be fully screwed down before any contact with water. It is the only real entry point for water on a watch. For that reason, our 2-year warranty does not cover water resistance: we cannot guarantee a step we don't perform on your behalf. It does, however, cover any manufacturing or assembly defect.

Case diameter is only a choice on certain models: the SEIKOJUST (36, 39 or 41 mm) and the SEIKODATE (39 or 41 mm). Our other families come in a single diameter, listed in the model's specifications — 41 mm for SEIKOAK, 39 mm for SEIKOCUB, and so on. If no size selector appears on this page, the model comes in one size only.

Which diameter should you choose?

• 36 mm: the most discreet, elegant and dressy. Ideal for wrists of 14 to 17.5 cm. A favourite for a feminine or vintage look.

• 39 mm: the reference size, versatile and unisex. Ideal for wrists of 16 to 20 cm. Our recommended size, classic and sporty at once.

• 41 mm: more presence on the wrist. Ideal from 18 cm up, or if you like a watch that gets noticed.

How do you measure your wrist?

Wrap a tape measure (or a piece of string you then hold against a ruler) around your wrist, just above the bone. Note the circumference in centimetres and pick your size accordingly.

Adjustable bracelet included 🔧

No need to worry about length: every watch ships with an adjustment kit to remove links and fit the bracelet precisely to your wrist. Sizing takes a few minutes, no watchmaking knowledge required, using the small tool included in the box.

Our Seiko mods are fully customizable from A to Z: case, dial, hand color, bracelet type (Oyster steel, Jubilee, rubber, or silicone), bezel, and even your logo or an image engraved on the dial, a service very few makers offer.
