Overview

• 904L

• Sapphire

• Automatic

The Nauteiko Openheart Blue stands out for its blue dial with open-heart window, allowing you to appreciate the automatic movement in full action, bringing dynamism and elegance. The 41 mm case in 904L stainless steel offers solid and refined finishing, while the contrast between the intense blue dial and silver details conveys a contemporary and exclusive style.

Designed for those seeking a striking yet sophisticated watch, this design combines highest quality materials with reliable mechanics. The 904L steel bracelet ensures resistance and durability, the scratch-resistant sapphire crystal maintains impeccable clarity, and the original Seiko NH38 automatic movement guarantees precision and reliability, visible through its open-heart window.

Shipping & returns

Insured, tracked shipping. Each watch is assembled to the configuration you choose, so it is excluded from the right of withdrawal; if it arrives faulty or is not what you ordered, we fix it fast at no cost.

FAQ

Is it ready to wear when it arrives?

Yes—assembled, inspected and shipped to your door.

How long does shipping take?

10–15 business days. Your watch goes through assembly, checks and final inspection before shipping.

Can I return it if I change my mind?

No. Your watch is hand-assembled to the configuration you choose, so it is excluded from the right of withdrawal (Art. 16(c), Directive 2011/83/EU). If it arrives faulty or is not what you ordered, the legal guarantee applies and we cover it.

What does the warranty cover?

The Roman Watches commercial warranty covers the movement and the assembly for 1 year. In addition, and independently of it, the legal guarantee of conformity — 2 years in the EU, 3 years in Spain — covering the movement, assembly and materials under normal use: we repair or replace at no cost. It does not cover water ingress: water resistance is 3 ATM (rain and splashes, no swimming, diving or showering), and a watch with moisture inside is not covered.

Will the watch look exactly like the photos?

Yes. The configuration and finish are exactly as shown in the photos.

Can I change my configuration after ordering?

If you contact us quickly, we’ll do our best to update it before processing.
