The Standard version delivers a precision of ±7 seconds per day, regulated at +3 seconds, corresponding to a daily variation of –4 to +10 seconds. It features finely sanded bridges and a solid, sanded oscillating weight pad printed with the logo, providing an accessible introduction to automatic watchmaking — as seen in the Classic Dream.
The Elaborated version, used in models such as the Le Locle and PRX, achieves an accuracy of ±5 seconds per day, regulated at +3 second, corresponding to a daily variation of –2 to +8 seconds. It offers enhanced finishing on the oscillating weight that can be skeletonised or engraved with the Vague du temps pattern, reflecting a higher level of craftsmanship.
Finally, the COSC-certified version, integrated into the Ballade, combines the same ±5 seconds per day precision, but regulated at +1 second (–4 to +6 seconds per day), with chronometer certification obtained through a rigorous testing process. This level exemplifies the pinnacle of Tissot’s technical and aesthetic expertise.
