Hi guys. Need some help to authenticate this Seiko LM. Posted as the 5606 8150 but I suspect it’s a typo because further pictures (I asked the seller later on) of the caseback shows it to be the 5606 8130. This guy is selling it on eBay. Said it was to slot it together with his Seiko collection but now not into Seiko anymore so he’s selling it off. He bought it overseas from another seller as well. He claims his do not have the quickset issue which is quite an issue with the 5606. This is the link: https://rover.ebay.com/rover/0/0/0?m...2F312555424417
His reserve bid is in the range of RM500 - RM600 so about USD140?
Would greatly appreciate some advice from anyone. Thanks!
