How Mechanical Watches Work: A Manufacturer’s Insider Guide
As a mechanical watch manufacturer with over 15 years of OEM/ODM experience, we specialize in custom movement modifications, rare material applications, and brand-specific designs. This guide offers an insider’s look at how mechanical watches work, our customization capabilities, and the wholesale process — from 50-unit minimum orders to 30-day delivery — all meeting CE, FCC, and RoHS standards.
Understanding the Core Mechanism
The Movement: The Heart of the Watch
A mechanical watch is powered not by a battery, but by the controlled release of energy stored in a tightly wound mainspring. When wound—either manually or via an automatic rotor—the mainspring stores potential energy. This energy passes through a gear train, a precision arrangement of wheels and pinions that reduce speed and transmit torque to the escapement.
The escapement acts as a gatekeeper, releasing energy at fixed intervals and allowing the balance wheel to oscillate at a constant frequency (commonly 21,600 or 28,800 vibrations per hour). This regulated motion drives the smooth sweeping second hand characteristic of mechanical watches.
Our manufacturing expertise includes:
-
Movement Complications: Adding skeletonized bridges, moonphase displays, GMT functions, and tourbillon cages for enhanced aesthetics and functionality.
-
Movement Origins: Selecting reliable Japanese automatic calibers for volume production or high-grade Swiss movements for luxury positioning.
-
Performance Tuning: Adjusting beat frequency and power reserve—from 40 hours to over 70 hours—for extended wear.
Materials & Engineering Standards
The movement is encased in a case designed for both protection and style. We utilize:
-
Titanium Alloy: For an optimal strength-to-weight ratio.
-
Carbon Fiber: For sporty durability.
-
Blue Sandstone: For a distinctive premium finish.

Our cases and seals ensure 50M water resistance through advanced gasket optimization and screw-down crown technology.
All components are manufactured under ISO-aligned processes and undergo rigorous assembly inspections with tolerances within ±0.02mm, ensuring precise timekeeping and product longevity.
OEM & ODM Collaboration Process
Step 1 – Design & Specification
Clients provide sketches or reference models; we advise on feasibility and technical refinements.
Step 2 – Prototype Development
We create working samples with your specified movements, materials, and branding—using laser engraving, dial printing, or rotor customization.
Step 3 – Mass Production
With a flexible MOQ of 50 units, our in-house assembly and quality control teams maintain consistent standards across batches.
Step 4 – Certification & Compliance
Each watch undergoes waterproof testing, movement accuracy checks, and is shipped with CE, FCC, and RoHS certifications.
Step 5 – Delivery
Typical lead time is 30 days from sample approval to final shipment. We have export experience to over 50 countries.
Proven Track Record in Brand Partnerships
Over the past decade, we have supplied over 100 watch brands worldwide, including established names such as Oblvlo and Angles Watches. Our collaborations span boutique luxury lines to large-scale promotional projects, showcasing our ability to adapt to diverse brand identities and market demands.
