Timex 2025 Perpetual Calendar. However, if the date ever slips out of the correct adjustment, it is easy to reset the perpetual. This year, in 2025, we know that three of the most prestigious brands will be celebrating important jubilees, as well as specific models reaching significant anniversaries.

The key part for me was aligning the date window perfectly. Workers at the timex factory preset the watch to the correct date, including the month and year.
