Swiss Ronda 515 GMT Movement Quartz Multifunction 24 Hours Hand - Gmt Date 3 Hands
The Ronda 515.24H (often referred to as 515H or 515/24H) is a reliable, feature‑packed Swiss quartz movement from Ronda’s 500 series. Its standout feature is a central GMT hand, which enables quick reading of a second time zone (24‑hour display) in addition to the regular timekeeping.
Key advantages include:
-
Precision & durability – Swiss‑made quality ensures consistent accuracy and long service life.
-
Versatile functions – Beyond hours, minutes, seconds, and date (at 3 o’clock), the powerful stepping motor drives the GMT hand smoothly.
-
User‑friendly design – Incorporates a power‑saving mechanism that reduces energy consumption by about 70% when the crown is pulled out. The movement is serviceable (not disposable), and its high interchangeability makes it popular among watchmakers for easy assembly and replacement.
