Recently bought my first Sinn 356SA (used )from a member of this forum. It only came with watch head, warranty card and a Sinn case and nothing else. Upon receiving the watch I didn't give it a second thought as the watch was fairly new (warranty card dated early 2018)
However just today I've noticed there are blue blemishes on several of the hour markers - they are actually quite noticeable to naked eyes (on the 7 and 8 hour markers)- almost looks like someone used a ballpoint pen to draw on it. You can also see them with a loupe on the 10 and 11 hour markers.
Is this normal for Sinn quality? The warranty card's serial number does match with the case back.
At this stage I have contacted the seller and Sinn to see if this can be sorted. Just hoping this is not a counterfeit.
