Ronda 519

Ronda caliber 519 is a quartz movement with a 3.0 mm height. It features a Big Date complication with an unconventional date wheel that continues past 31 to 39, then flips to 00 before advancing to 01, requiring manual date adjustment each month rather than only on months with fewer than 31 days. The movement includes a power saving mechanism that reduces consumption by approximately 70% when the crown is pulled out.
