NAWCC Announces WS-119 Workshop on Wheel & Pinion Cutting Techniques
NAWCC Announces WS-119: Wheel & Pinion Cutting Workshop
The National Association of Watch & Clock Collectors (NAWCC) has announced a new educational workshop, WS-119: Wheel & Pinion Cutting Using the Table Top Milling Machine. This hands-on course is designed for watchmakers and horology enthusiasts seeking to master the precision art of gear cutting for watch repairs and custom movement modifications.
Scheduled as part of NAWCC's continuing education program, WS-119 focuses on teaching participants how to produce accurate wheels and pinions—the fundamental components that transmit power through a watch movement—using accessible table top milling equipment.
Course Overview and Learning Objectives
The WS-119 workshop covers essential techniques for fabricating watch wheels and pinions, which are critical elements in the gear train of any mechanical timepiece. Participants will learn:
- Fundamentals of wheel and pinion geometry in watch movements
- Setup and calibration of table top milling machines for precision horological work
- Cutting techniques for various gear ratios and tooth profiles
- Quality control and measurement methods for ensuring accurate gear meshing
- Material selection for durable, long-lasting components
Why Wheel and Pinion Cutting Matters
Wheel and pinion cutting is among the most technically demanding skills in traditional watchmaking. These tiny gears—often measuring just a few millimeters in diameter—must be manufactured to exacting tolerances to ensure smooth power transmission and accurate timekeeping throughout a movement.
For hobbyists engaged in Seiko modding projects, understanding gear mechanics provides deeper insight into how movements function, even when working primarily with pre-manufactured components.

About NAWCC
The National Association of Watch & Clock Collectors is a leading organization dedicated to the study, collection, and preservation of horological history. NAWCC offers educational programs, workshops, and resources for both professional watchmakers and passionate collectors. Their workshop series provides structured learning opportunities in traditional and modern horological techniques.
Benefits for Seiko Mod Builders
While Seiko modding typically involves swapping pre-made parts rather than fabricating components from raw materials, understanding wheel and pinion mechanics enhances a builder's overall knowledge of movement architecture. This foundational knowledge proves valuable when comparing different Seiko movements or diagnosing issues in custom builds.
The principles taught in WS-119—precision measurement, material selection, and machining accuracy—directly apply to other aspects of watch modification, including case fitting, dial alignment, and water resistance considerations covered in our water resistance testing guide.
Registration and Resources
Interested participants should visit the official NAWCC website for current scheduling, pricing, and registration details for WS-119. The workshop represents an excellent opportunity to learn a rare craft skill under expert instruction.
Frequently Asked Questions
What is a wheel and pinion in a watch?
A wheel and pinion form a gear pair in a mechanical watch movement. The larger gear (wheel) meshes with a smaller gear (pinion) to transmit power from the mainspring through the gear train to the escapement, ultimately driving the hands. Each gear pair must be precisely cut to ensure accurate timekeeping.
Do I need prior watchmaking experience for WS-119?
While specific prerequisites should be confirmed with NAWCC directly, wheel and pinion cutting is generally considered an advanced horological skill. Participants should have a solid foundation in watch assembly and disassembly before attempting precision gear fabrication.
Can these techniques be applied to Seiko movements?
The machining principles and precision measurement skills taught in wheel and pinion cutting workshops are transferable across different movement types. However, most Seiko mod projects use pre-manufactured replacement parts rather than custom-cut gears.
