The push-buttons are not screw-down.

Condition

This watch has been overhauled by our store and is ready for immediate use.

As it is a USED item, there is no waterproofing guarantee.

The original bracelet is sufficiently long and can accommodate a wrist circumference of up to 194mm.

The crown screws down properly.

When screwing down the crown, it is recommended to carefully find the threading
and screw it down slowly to avoid damaging the screw threads.

There are stains around the outer edge of the dial and a small crack in the luminous paint of the hour hand.

How to operate the ETA7750

Unlock the screw-down crown and perform the following operations:

Manual winding: Rotate the crown upwards in its normal position.

Time setting: Pull the crown out two clicks and rotate it downwards (the seconds hand stops when pulled out two clicks).

Quick-set date: Pull the crown out one click and rotate it upwards.

Quick-set day: Pull the crown out one click and rotate it downwards (reverse order: SUN→SAT→FRI).

While the quick-set date function is convenient, operating the quick-set function when the watch indicates between "9 PM and 2 AM" can cause damage to the gears.
If you need to use the quick-set function, it is recommended to adjust the time to around 6 AM/PM first.
