Girard Perregaux was the first Swiss manufacturer to put 36000 bph watches into production in the mid sixties (the Seiko Lord Marvel was developed at concurrently in Japan, GP probably had the earliest commercial introduction). Here are a few of mine (the ladies model is only 28800 - Seiko retains the distinction of being the only mfg to produce a 36000bph for ladies). In the 70s GP used hi beat movements in the chunky styles of the period, but that aesthetic (if that word can even be applied to 70s styling) is represented in my collection by other brands.
