Measurement Guidelines
To ensure an accurate fit, measure along the surface of the leaf spring. Note that eye-to-end measurements may vary over time due to the spring flattening with use. If you have any questions, contact the experts at Spring Works for assistance or open our chat for AI responses to common questions.

Dies after a Year
Color: 5566-ZP-white face
Watch worked fine for about a year, then just stopped working - just like that. No amount of shaking or gentle impacts would get it to start ticking again.
I'd also say my biggist issue with it was it was always difficult to tell which hand was the second hand and which hand was the minute hand since they're both the same color and thickness. Wish the hour and minute hands were a little thicker so they'd stand out a little better and/or that the minute hand was a different color so it was offset. Resulted in having to study the watch to get the time instead of a quick glimpse to see what time it was. Irritating after a while.
