Custom watch services Overview

TSNwatch was established in 2025, evolving from our original brand, iwatchcase. We started by manufacturing watch cases and gradually expanded into dials, hands, crowns, bracelets, buckles, and more. It has been nearly 10 years in this industry. TSN is not a new team, but an upgrade of iwatchcase.

We are proud to say that we now have the capability to produce fully customized high-end watches. On this website, I will share detailed information about every aspect of custom watchmaking. The content is still being refined, but if you are ready to start your watch project, feel free to contact us — I will get back to you very quickly.

What really matters is understanding your needs, being able to absorb your ideas, and even offer helpful suggestions. From simple logo customization to fully bespoke projects, we support every stage of your watch development.

Patient communication

No matter your country, language, or experience level, we communicate patiently and confirm every drawing and requirement carefully. You can request revisions anytime, and we provide timely updates. For difficult-to-manufacture parts, we proactively suggest adjustments to ensure mutual understanding and the best result.

Professional Manufacturing

We handle every production step with care. From material cutting, fixture preparation, CNC setup, and tool installation, to drilling, polishing, and assembly, experienced professionals oversee each process to ensure the precision meets your requirements.

Fast delivery

We strive to respond on the same business day to minimize delays from time differences. When necessary, we expedite requests and carefully schedule production to ensure on-time delivery.
