“I purchased 20mm and 22mm spring bars. They were shipped immediately and work as advertised. Very happy with my purchase. Only constructive comment is to identify the size of various spring bars on the small plastic envelope the spring bars are packaged in. It's difficult to eyeball a 20mm versus 22mm spring bar. Would be a bigger challenge if I had ordered 21mm spring bars as well. Just an FYI. Very pleased with Long Island Watch.”
