Shipping

All watches are bespoke and are made to your order and take approximately 4-7 days for your watch to be built, tested, and prepared for shipping.
We always aim to deliver faster than this time frame but it ensures we can take the necessary measures to allow us to perfect every detail of your watch with precision and care. Once completed, we ship your timepiece via express delivery—worldwide.

Once complete, your watch will be shipped with free worldwide delivery where all import duties and taxes are covered by us, which typically takes 5-10 days, depending on your location.

Warranty

We include a free one-year warranty with every watch we build—not because we have to, but because we’re confident in the quality of our craftsmanship.

Each timepiece is assembled with precision and care, using high quality, genuine components you can trust. This warranty covers all manufacturing defects and mechanical issues under normal use, because when you invest in one of our watches, you deserve lasting reliability.

While we don’t cover accidental damage or misuse, we’re always here to help keep your watch ticking.

Discover the ultimate combination of precision engineering and timeless style with the Custom Seiko Vintage MilSub GMT JB Mod. Built with premium materials like 904L stainless steel, this 44mm timepiece is designed to withstand the rigors of everyday use while delivering a striking, modern look. Perfect for watch enthusiasts who appreciate quality craftsmanship and reliable performance.

With the NH34 GMT Automatic Movement, this watch not only tells time but also tracks a second time zone, making it ideal for travelers or those who need to keep track of multiple time zones. Its domed sapphire glass offers superior scratch resistance, and the 42-hour power reserve ensures that it will keep ticking even when you take a break.
