Q1: What is the difference between “Swiss Made” and “Swiss Parts” versions?
A: The Swiss Made version (5 jewels, gold-plated EOL) has higher jewel count and premium finish, offering better long-term reliability. The Swiss Parts version (1 jewel, nickel-plated) is more economical while maintaining Swiss quality standards.
Q2: What does EOL stand for?
A: EOL stands for “End of Life” – a battery depletion indicator. When the battery is low, the seconds hand jumps every 4 seconds instead of every second, signaling it’s time to replace the battery.
Q3: Does this movement come with a battery?
A: No, the battery is not included. You will need to purchase a 371 / SR920SW battery separately.
Q4: What is the hand fitting height?
A: Hand fitting height 1 indicates standard hand height. This refers to the distance from the movement top plate to the hand seating position.
Q5: What watches use the Ronda 753 movement?
A: The Ronda 753 is commonly used in compact ladies‘ watches, rectangular watches, and small case designs due to its ultra-thin 2.5mm height and 5½‴ size.
