accessories
Outer box / Inner box / Instruction manual / Manufacturer OH details (April 2020) / Card reader etc.
*The instruction manual has some damage. There is some damage to the inner box lining and pillow.
Although it is currently usable it may become sticky if stored for a long period of time so it may be better not to use it.

condition
*Used A
*This is a very clean used item with few small scratches and no signs of use.
The previous owner performed manufacturer complete service in April 2020.
The contents are (chronograph hand push button insert push button complete service 06 additional work on exterior finishing).
There are small dents on the back cover but the damage is not significant enough to be of concern as it is a used item.
I couldn't find any scratches on the coating. I think it's either a minor scratch on the coating or some sort of action was taken such as replacing it.
There are no scratches on the glass itself.
The genuine rubber belt is in good condition with little signs of use but there is some superficial deterioration near the lugs. It's not something that could cause damage and you won't notice it unless you look closely so I don't think it's a problem in practical use.

*The HUB4100 movement has gone through several minor changes so there are many different types. Initially it was based on the ETA Valjoux 7750 but I believe it is now based on the ETA replacement movement Sellita SW500.
If there is an ETA stamp it is an ETA base and if there is no stamp it is a Sellita base. The timing of the change is likely to be around 2015.
There are four types of ETA7750-based models: *It is easy to tell that it is a 7750 *Without a cover it comes with a Trio-Bis adjustment device *With a cover it comes with a Trio-Bis adjustment device and *With a cover it comes with a 7750 adjustment device. I think it will be.
The one attached to this individual is the fourth type.
*I think the type that has a cover and has a speed adjustment device that feels a little luxurious is based on the Sellita SW500 and has been used from around 2015 to the present.
