I bought a Marine Diver for my Dad almost 20 years ago for his 75th birthday. He wore it almost everyday and he had a Rolex Air King, Seiko Bellmatic and an Omega Gold Constellation to choose from amongst his small collection.
Never had an issue with the watch and had a routine maintenance service, nothing was wrong with the watch, about 10 years after I gifted the watch to him.
My youngest son has been wearing the Marine Diver since 2020 after my Dad passed and it still keeps excellent time.
