I don't know if many Middle-Earthers knew this, but Gollum was a budding watch enthusiast before his demise...
The only time I find drilled lugs useful is when removing a bracelet. Sometimes they can be a pain to remove. With a regular strap I prefer to remove it from the back. With just a little bit of practice you can become pretty skilled at removing straps. I still put a little tape on the lugs just in case. Not having drilled lugs is no big deal.
I preach about Swatches being good for how you don't need any special tools to maintain them. A coin and a paperclip is all you need. Hell, in a pinch, a piece of paperclip can substitute if the original retainer bar gets lost.An unfolded paper clip is my go to tool for drilled lugs strap change, works a treat.
And then there's Seiko that puts shoulder-less spring bars on their SKX that doesn't have drilled lugs! It's easier to hack off the strap into pieces than remove the spring bars. What kind of sadistic monsters are making these decisions at Seiko?!?I've never done any "pull tests" myself but I tend to believe that a shoulder-less spring bar would offer greater shear/tear strength than a traditional spring bar based on how far the shoulder-less spring bar goes into the lug. Also I like the design aesthetic they bring to a watch, tool watch or not.
