Hamilton Khaki watch. Analog watches may be superfluous and pointless in an era of phones and smart watches, but I actually really enjoyed learning about horology and researching more about movements and brands, and purchasing a well made time piece was just plain ol' fun.
Watches are amazing, they're one of the last connections to my previous life as a mechanical engineer (software now). JLC, NOMOS, and Zenith are wonderful brands to check out.
