07
Pre-Shipment Audit
100% cosmetic sign-off, crown operation audit, and serial-numbered packaging.
Accessible Production
Start Small. Scale With Confidence.
Traditional watch manufacturers often demand orders of 1,000 to 3,000 units before production becomes viable. Fullion eliminates prohibitive capital lockups with dedicated pilot production cells.
Pilot Run Framework
100-300 pcs Pilot MOQ
Traditional factories demand massive production runs that paralyze emerging watch brands with unsold inventory. Fullion supports pilot production runs of 100 to 300 pieces so you can validate your concept, test Kickstarter or pre-orders, and launch your brand with minimal capital exposure.
When pre-orders convert and your brand is ready to scale, our automated multi-axis CNC machines ramp production into 1,000+ piece batches directly with no re-engineering penalties.
Validation Speed
7-14 Days Rapid Sampling
Depending on design complexity and component requirements, initial functional prototypes can be fabricated in as little as 7 to 14 days after technical specifications and CAD are confirmed.
Holding a physical prototype allows you to verify case proportions, bezel click feedback, dial legibility, crown winding feel, and bracelet drape on wrist before investing in commercial volume tooling.

Common Questions
Frequently Asked Questions
Clear answers to the most common technical, logistical, and commercial questions watch brand founders ask before partnering with Fullion.
What is your MOQ for custom watches?
Our pilot MOQ typically starts from 100 to 300 pieces depending on case complexity, caliber selection, and custom component tooling. This allows microbrands and startups to launch with minimal capital risk before scaling.
Can you manufacture a watch from my own design?
Yes. We regularly manufacture from hand sketches, 2D vector files, 3D CAD files, reference timepieces, or physical samples. Our engineering department translates your aesthetic intent into production-ready blueprints.
Can you help with watch design and CAD engineering?
Yes. If you do not have engineering drawings, Fullion provides complete DFM (Design for Manufacturing) support, 3D CAD modeling, exploded component blueprints, and movement integration analysis.
Can I start with a functional prototype before mass production?
Yes. We strongly recommend functional prototype sampling. You receive a finished physical sample to inspect dimensions, finishing, dial texture, hands alignment, and water resistance before approving full batch production.
Can you execute an NDA before receiving design files?
Yes. We treat client intellectual property with strict confidentiality. We execute bilateral Non-Disclosure Agreements (NDAs) before you share confidential sketches, technical drawings, or branding assets.
Which movements can you source and assemble?
We source authentic calibers directly from authorized Japanese and Swiss channels, including Seiko (NH35, NH38, VK meca-quartz), Miyota (9015, 8215, 2035), Swiss Sellita (SW200, SW510), ETA, and Swiss Ronda quartz.
Do you offer PVD, DLC, and gold plating finishes?
Yes. We offer a full spectrum of surface treatments including high mirror polish, satin brushed, bead-blasted matte, PVD black, DLC (Diamond-Like Carbon), 18K yellow gold, and rose gold PVD coating.
How long does production take?
Rapid sampling can be completed in 7 to 14 days after CAD freeze. Commercial mass production generally requires 35 to 45 working days, depending on dial complexity, movement availability, and order volume.
