$40,000 would support a Torah family for two years. Where’s the heter to spend it on a watch?
By that argument where is the Heter to Eat Sushi, Drink Cabarot Soveignon and drive a New Car.
One could eat bread and water and give the “excess” money to a torah family. Chicken, Kedem Concord Grape and a 1992 Ford Wagon are just fine
