https://www.christies.com.cn/lot/lo...e-18k-gold-5993009/?intObjectID=5993009&lid=4 this is beautiful and different with other 13zn gold case . The lug is small but looks good . I can’t see any other same reference, the watch is amazing with the two tone dial . Small longines long and thin blued hands . does any expert with more details about 5090 ?
This watch was bought by an OF member years ago. See here: https://omegaforums.net/threads/13zn-chronographs-inquiries-and-information.32929/page-4#post-485172 There were many Longines 13ZN references, and most are not specifically sought-after. What information are you looking for?
