Ronstan Clear Start™ Race Timer - 65mm (2-9/16") - Black/White

The Ronstan Clear Start Race Timer in 65mm (2-9/16") black and white is purpose-built for motorsport enthusiasts, track day coordinators, and competitive drivers who demand precision timing at the starting line. Whether you're managing autocross events, drag racing competitions, or formal track sessions, this mechanical race timer eliminates electronic dependency and provides instantaneous visual feedback to all competitors and officials. Its large, easy-to-read face design ensures visibility from a distance, making it an industry-standard choice for racers and event organizers who cannot afford timing failures.

Built by Ronstan—a trusted name in motorsport timing and marine instruments—this 65mm timer uses a mechanical dial mechanism that requires no batteries or electronic components, eliminating the risk of power loss during critical race moments. The clear start design features a split-second sweep hand and bold black markings on a white background, engineered for contrast and readability in variable lighting conditions typical of outdoor track environments. The robust construction handles the vibration and impact common to race pit areas, while the compact 3 x 3 x 5-inch form factor mounts easily to timing stands, control booths, or portable equipment without bulk.

This timer is ideal for SCCA members, drag strip officials, autocross organizers, and serious track-day participants who need reliable, non-electronic timing verification. Its mechanical operation makes it essential backup equipment at sanctioned racing events where timing integrity is non-negotiable, and it remains the preferred choice by experienced race directors who value simplicity and dependability over digital complexity. At 0.35 lbs, it integrates seamlessly into timing setups without adding weight or complications to mobile or fixed installations.
