Tookie Mechanical Stop Watch, SXJ504 Handheld Sports Chronograph Alarm Mechanical Stopwatch Running Timer, for Sports Referee Running Cycling Count Timer

This type of Stop Watch is so easy to use and helps me to time my excersizes.😊

I was excited for this product because it appeared to be exactly what I wanted. I wound it once and stopped just when the resistance changed. It was working for a few minutes and was reset to the zero position about 5 times before it stopped working. I would not recommend this product.

Good stop watch, but no water protection, so I'm returning.

I purchased this stop watch Aug '21 and even with minimum daily use, it's garbage! Do not purchase if accuracy is a requirement. Sweep arm does not reset to 0; it resets three clicks to the left of 0. Additionally, the sweep arm does not stop but continues to run after you depress the button, rendering it useless to record the time elasped.

Wow should have read the reviews first. Starts, stops, next crown push, nothing, next, restart. Will not go to "Zero".

it just stops. i returned it thinking it was just a fluk got another one same thing. justs stops. could be bad battery i suppose. but shouldn;t have to change it brand new.

Two of these stopwatch did stay synchronous after 1 hour.

worked great, easy to read and operate then next day it didn't start
