Bergeon simply makes the best tools in the watch industry. Their spring bar tools are expensive, but they are very strong, precise, and long-lasting.
The 6767-F is a steel-bodied tool with hardened steel tips. The pusher tip is 0.8mm and works with most drilled lugs. The forked tip is 1.2mm wide and thin enough to easy get in between the strap and the lugs (and should work with most bracelet end links). Both tips are about as strong as they come, and will last you a long time. In case you need to replace the tips, we sell them separately here.
