[Prospex Baby Tuna SRPH77K1] New (to me) watch passed down from my aunt. Gunky though, will this be easy to clean?
Since 2022 this was one of my aunt's watches. She gave it to me earlier since she was downsizing and this was one of the least worn in her rotation. After a strap change, I'm loving how it looks~
Since this is a diver's watch, I plan to take this swimming next week during a beach trip with friends. However I did see a bunch of gunk as shown in pics 3 & 4. Watch shop guy told me it wasn't rust and just needed light brushing/cleaning and metal polishing.
Are they right with their diagnosis?
