Check out NJ times in Ginza. According to the web site they have one 'Tintin' in store. I purchased mine there late last year. Transaction went well and I got an amazing price. I had the bracelet adjusted however they damaged some of the screws when putting the band back together. I only noticed this after I got back home. I took the watch to Omega here in Melbourne and they replaced the damaged screws for me at no charge. I had completed a serial number check on the watch I was looking at and all legit from my research. As I have reported before as these watches are drying up, NJ times and other dealers are sourcing supply through HK at the big auction houses. My watch was manufactured in 2016 after researching info with Omega but I have no complaints international warranty still ok as all the cards present and stamped. My suggestion if this is your first omega I would probably buy it if you are happy with the watch you see as is, and don't let them touch it too much try it on if it is too big no problem, take the watch to OB when you get home and get them to size it for you if you don't feel confident. English with the staff as very limited so it was just too hard to explain things in more detail and most staff from experience as just sales people to assist with making the sale easier. Good luck. if you are happy with the item you see, do share your photos! There will never be another Omega TinTin, ever!! Love it/wear it.
