Hi everyone, My first post here, hoping someone can help me figure out what's going on with my Tag Carrera... I have noticed strange marks on my watch face a few days ago. At first i thought it was just dirty or foggy and that a quick wipe would fix it but no luck. The marks go away when wiped with my thumb or soft cloth but come back within 5 minutes. I have also tried washing with soap and warm water...no result. When i first take the watch out of my drawer to wear in the morning, there are no marks on it and the glass is absolutely clear. However, when i wear it, the marks come on after maybe 15 minutes (presumably after the watch warms up due to skin contact?). The pattern of the marks does not change and is always exactly the same. I have not banged or scratched it anywhere nor used any abrasive chemicals to clean the sapphire glass. The watch is kept in my bedroom closet, in a drawer at night. Temperature in the room is around 18 to 20 degrees Celsius. There have been no environmental changes since the day I have purchased it and it is even kept in the same drawer and room since day one. The bizarre thing is that there is even a reflection outline on the area above the date/day box and Tag logo. Picture attached. I purchased the watch brand new from a reputable authorised dealer (physical store, UK) and have owned it for a little over 3 years. Have not serviced it yet. A few pictures are attached so you can have a look. Please note that the pictures with marks are taken before cleaning on my tshirt and the clean ones are taken after. The marks came back a few minutes after wiping. Does anyone here have any idea what's going on? Thanks in advance!
