Best Praise
+24 pts“1 year in. Am I enthusiast yet? Tudor BB58 - bc Reddit IWC Mark XX - sophisticated GADA Rolex Datejust 36 - daily driver Casio F91W - classic god tier JK don’t kick me out. Seriously, I need validation… Seiko SPB143 - Diver. It’s cool. I like it. Farer Lander GMT - I fall in and out of love with this one. I can’t decide if I want to keep it or sell it and actually get a Mark XX. I’m fickle. Christopher Ward C63 Sealander 36 - Literally daily driver. It’s lightweight, easy to read, and nobody asks me about my Rolex. But also bc I can’t get a Rolex. G-Shock GWM5610 - for when ~~I’m walking the dog or sitting in the jacuzzi~~ training for triathlons.”

+5 pts“Even if the SPB143 shares some of the DNA of the OG 62mas, it’s just such a different watch that it’s really not a good substitute. At least not for myself. The SPB151J1 for instance, is a lot closer to the OG Willard than the SPB143 is to the 62mas.”
