SEIKOLUS rosegold blue

The SEIKOLUS rosegold blue carries the same DNA as the great collectible sports watches: an elegant curved case, an integrated bracelet that becomes one with the case, and attention to detail that sets it apart. Its rose-gold case and blue horizontally-grooved dial form a warm, refined contrast. An instantly recognisable style, accessible and fully customisable.

Hand-assembled in France around a genuine Seiko NH35 automatic movement, reliable and proven, with date. Every watch is regulated and tested before shipping.

Technical specifications:

• Genuine Seiko NH35 automatic movement with date
• 316L stainless steel case, rose-gold finish, 40mm (excl. crown)
• Integrated bracelet matching the case, adjustable with the sizing kit
• Sapphire crystal, sapphire case back
• Water resistance: splash-resistant — reinforced 5 ATM option available

Fully customisable — dial colour, hands, custom logo. Build via our configurator.

Delivered with storage box and sizing kit. 2-year warranty. Lead time: approx. 2 weeks.

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.

Which size to choose: 36mm or 39mm?

Our SEIKOJUST cases come in two diameters to suit every wrist:

• 39mm: The reference size, versatile and unisex. Ideal for wrists from 16 cm to 20 cm. Our recommended size for a look that is both classic and sporty.
• 36mm: A more discreet and elegant size, perfect for slim wrists from 14 cm to 17.5 cm. Highly favored for a feminine fit or a vintage / dressy style.

How to measure your wrist?

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

Adjustable bracelet included 🔧

No need to worry about length: every watch ships with an adjustment kit that lets you remove links and fit the bracelet perfectly to your wrist. Sizing takes just a few minutes, with no watchmaking experience required, thanks to 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.
