Where are your watches assembled?
We assemble all our watches in a private workshop in London, United Kingdom, but to reduce wait times for our customers, we may use partner workshops in other cities across the UK.
Are you affiliated with Seiko?
No, under no circumstances.
We use original Seiko automatic movements for their quality and reliability. Each watch is then assembled with custom parts exclusively for each client.
Are they waterproof?
Our watches are rated at 3 ATM water resistance, meaning they’re suitable for everyday exposure such as light rain or accidental splashes. However, they are not recommended for swimming or diving.
Water resistance can be affected by several factors, including an unscrewed crown, sudden impact, or extreme temperature changes.
If you require a higher level of water resistance for swimming or similar activities, please contact us prior to ordering so we can make the necessary adjustments.
Finally, please note that any water resistance markings on the dial are purely decorative and do not reflect the actual technical specifications of the watch.
