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?
Yes. You have 30 days from delivery to return it, even if it's a configured watch.
What does the warranty cover?
The Roman Watches commercial warranty covers the movement and the assembly for 3 years. 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.
