The watches you show as beaters would generally be on most of our wrists as prized possessions.
Yeah, but the Glycine has been designated the one true beater for most of my adult life. Was a $5 purchase from a pawn shop sometime in the mid-1980s. Thought it was cool to be using an old mechanical watch for hunting, fishing, and hiking. Soon became the oil changing, yard mowing, garden grubbing, chicken run cleaning watch. It was the beater long before I joined Omega Forums and learned what the term "beater" meant in a watch. Wore nice watches to the office so needed a beater.
Wore it for years without ever servicing it. Was quite accurate. Serviced it the first time and it was even more so. Remains one of the more accurate watches in the menagerie here. It ought to be promoted to vintage collectible status, but I think it'd become vexed with me if I retired it from duty. Great retirement watch for around the house.
