Good Morning, Forum! I survived roller skating intact; no new pain!! We refer to some of our favorite watches as ‘strap-monsters’; I’ve come to view this Omega nato as a ‘watch-monster’. It’s part of the Seamaster 75th Celebration, and the keeper on the medial side is marked Seamaster. Currently on the ST1, but I love it on the Gemini 4 and 3861. Have awesome days/nights Friends!
