An entire month dedicated to puffing and passing? We say “hell yes!”. Initially an April Fool’s joke, it’s now here to stay! This automatic watch has 0% THC and CBD but 100% of the original flavor. Characterized by its unmistakable green colors on a California dial and accentuated by the “devil’s lettuce” on the 12-hour mark, as well as a cheeky “4” at the 20-minute mark (get it?), this watch is dedicated to puffers and watch collectors alike. What’s more, you can now customize the 420 Cali with your initials or a caseback photo to make that the only one in the world!
