Notice to Buyers:

1 - Due to material costs and production time, we don't pre-produce watches. Our watchmakers start crafting your watch within 12 hours of order confirmation. Depending on complexity and materials, production usually takes 3–7 days. Custom orders may take longer — but good things are worth waiting for, aren’t they?

2 - Don't even think about comparing our watches with those so-called 'perfect replicas' under $1,000 - and definitely not with those cheap $500-or-less watches. Trust me, they're not even in the same league!

3 - Some countries get fussy about imports – chat with us first so we can ninja your package through customs.
