Mike987I taught SCUBA for couple years - used plenty of 100m watches; they are fine. Max depth for a rec diver is 40m, and you are going to be there for 5min not doing much as a) your air will be dropping like a rock and b) no decco stops. Is it a watch for a tech diver - no, is it perfectly fine for recreational diving - absolutely. 90% of the time you are going to be diving 10-20m range.
I had students using 50m watches without an issue. Additionally, nowadays you will have a dive computer as your primary timer. Interestingly, most of them are rated at 100m. There's been a depth rating creep in recent decades, as manufacturers try to upsale customers into more expensive models.
This one, from a reputable manufacturer and a good design, is plenty fine for recreational SCUBA.
