I wear my watch on one of two straps...the stock bracelet or a Nato or Zulu. Lately I've been switching them up quite frequently between various Natos' (and Zulus') and the bracelet. Yesterday I was going on a drive along the Fundy shore and since it was such a nice day I had my window down with my arm out the window. When I brought my hand back in I found my Ocean 44 dangling on the Nato after one of the spring bars had apparently failed and let go! I was in shock and also extremely thankful that I was wearing it on the Nato. I inspected the lug holes when I got home and found them fine...simple spring bar failure most likely caused by frequent strap changes. I've replaced the remaining spring bar with a couple beefier ones and will try not to make as many changes to the bracelet and back!
