商品説明
This is a Sinn 556 self-winding wristwatch.
The 556 is a model characterized by its highly legible design.
To ensure the dial legibility that is essential for pilots in the cockpit, the design features large, prominent indices.
The indices and hands are coated with luminous material, providing excellent visibility in dark conditions.
The case and bracelet are made of stainless steel.
The 38.5mm case size strikes an exquisite balance—neither too big nor too small—making it fit naturally on most wrists.
The thickness is kept to a modest 11mm, so it does not easily catch on shirt cuffs.
The case back is a skeleton design, allowing you to view the movement of the watch's heart.
The crown and case back are screw-down type.
The Sinn "S" logo is engraved on the surface of the crown.
The crystal is made of scratch-resistant sapphire.
Equipped with a Swiss-made self-winding movement, it features manual winding, hacking (seconds stop), and date quick-set functions, making it highly practical.
Operating Instructions
Manual winding: Unscrew the crown and rotate it upwards.
Time adjustment: Pull the crown out to the second click and rotate it downwards (the second hand stops in this position).
Date quick-set: Pull the crown out to the first click and rotate it upwards.
Operating the quick-set function while the watch hands are between 9:00 PM and 3:00 AM may cause damage.
We recommend moving the hands to around 6:00 before performing the quick-set operation.
Condition
The daily rate (instantaneous rate) measured by a timegrapher is as follows:
This is not a measurement based on 24 hours of operation.
Please consider these as reference values, as variations will occur depending on the winding level and usage environment.
Dial-up: +3 seconds, Crown-up: +2 seconds
As this is a pre-owned item, there is no waterproof warranty.
The glass has a linear scratch, but the dial remains clearly legible.
The crown screws down securely.
If the crown threads are damaged, they can only be repaired by the manufacturer.
Please handle with care to avoid damaging the threads.
The buckle features a double-locking mechanism.
It can accommodate a maximum wrist size of 194mm.
