There's no one position that will typically cause an automatic to lose time. Each and every mechanical watch is different, which is why the "trial and error" approach you took was a good one. Some watches may vary greatly when kept in different overnight positions, while other watches may exhibit only minor differences when their overnight position is changed. You may find that you have a watch that won't slow down or lose time no matter what position you keep it in. So, perhaps the best you can do is find out which overnight position causes it to gain the LEAST time, which, again, can only be determined through trial and error.

Good luck,
