Montevideo is 4 hours behind Geneva
Best overlap: 12:00 PM to 6:00 PM in Geneva is 8:00 AM to 2:00 PM in Montevideo.
Both offices are open during 12:00 PM to 6:00 PM Geneva time, which is 8:00 AM to 2:00 PM in Montevideo. Scheduling is forgiving here: with 6 hours of overlap, a missed slot just means picking another one the same day. Watch the DST gap — when Geneva changes its clocks and Montevideo stays the same, this window slides by an hour.
