Help me find a leather band for a gift

Hello everyone, I am new here. I just finished my undergrad and doing my masters in the fall and my father gave me one of his watches as a gift. Unfortunately, the leather band is falling apart. I am a student so I don't have much money, I saw watch bands go for 300+ from the JLC site. Are there other options that are cheaper that matches my watch?

I have a JLC Reserve de Marche, the number i got on the watch is 140.8.93
