When Biver poured in new life to the segment (amongst others), the movers and shakers were largely people who still lived through times, where mechanical watches were the only game in town. In a Veblenian sense they determined what was in and what not and that covered another generation.
Similar with motorcycles as a parable. There in Western countries the car supplanted them as a significant means of transport between the 1920s (USA) and the late 1960s (Europe). Still the industry kept on booming for many decades later, where the customers got older on average, with a higher disposable income. The only issue is that nowadays thereโs hardly new riders / customers entering the fray and the overall pool is dying out. More over 85 year old bikers than under 25 year old ones since the early 2000s in Germany for instance.
So I do not predict a demise of the watch industry in the next 15 years but it will be relatively hard going by about 2050. By then we will have hopefully acquired all our grails and our children will possibly no longer care ๐๐คท๐ปโโ๏ธ
