The power reserve indication and subsidiary 30 minute register were marked with a 60 minute scale, allowing for greater chronograph timekeeping accuracy and the compact case design and round pushers were a gentle nod back to the Reference 3970. At 40mm, the reference 5960 is very wearable and a stellar example of Patek Philippes modern high complication timepieces.
