Sorry what do you guys mean by buy the seller?


I sold off my Seamaster Professional 41mm for RM4.8k with box last Sept. On hindsight, I would have kept it in my collection as it was more wearable compared to my subsequent XL diver watches e.g. Seamaster Planet Ocean 45.5mm. And the wavy details on that dial was simply mesmerising. Having an ETA movement is good news to me actually- it's a reliable and dependable workhorse that is the backbone of the Swiss horological backbone, and easily-serviced anywhere.
Buying the seller means to assess the seller first. Ask for his name card and check his credentials. If he has title(s) e.g. Tan Sri, Dato, etc and/or is of a higher work class e.g. Director, GM, etc and/or knows about his watches (engage in a dialogue with him- most WIS would be willing to share their knowledge and talk about watches until the cow comes home), then you should be in good hands. After all, these people are unlikely to risk tarnishing their reputation for a mere tuppence. But if the owner acts shifty and/or doesn't want to give his name card and/or knows nothing about his watch, then I would have red flags raised upon. Just my 2 sen.
