Design your watch

The Process

Custom Watch Builds — Built Around Your Vision

At KOULUOLANG, we don’t just build watches — we bring your vision to life through custom Seiko watch mods that reflect your style.

Whether you’re after a clean, minimal design or something bold and unique, every timepiece we create is custom-made to your exact specifications using premium components.


🎨 How It Works:

1. Share your idea — It could be a photo, sketch, description, or just a concept.
2. We design it together — We'll guide you in selecting the ideal dial, bezel, case, hands, and strap.
3. We build it from scratch — Using high-quality materials like sapphire crystal, ceramic bezels, Seiko automatic movements, and 316L stainless steel.
4. You receive your one-of-a-kind timepiece — A fully hand-assembled Seiko mod, crafted just for you.


🔧 Built With Premium Materials:

  • Sapphire crystal glass

  • 316L stainless steel

  • NH35 / NH36 / NH34A / VK63 / NH70 Seiko movements
