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 3153 is a plastic-bodied tool with hardened steel tips. The body is hexagonal to prevent it from rolling, and it features a useful millimeter scale etched and painted for measuring your lugs and straps. The pusher tip is 0.8mm and works with most drilled lugs. The forked tip is 3mm wide and thin enough to easy get in between the strap and the lugs. 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.
Please note: The forked tip is too wide to fit in the end links of most metal bracelets, meaning this tool isn't suitable for bracelet removal or installation.
