Optimize the security of your dive watch strap with our double-flanged 316L stainless steel spring bars. With a 2.5mm shaft diameter and 0.8mm tip diameter, these heavy duty bars won't bend or break, and are perfect for a secure fit. Be sure to measure the holes of your strap to confirm compatibility with this slightly larger 'fat' spring bar. Available in 18mm, 19mm, 20mm, 21mm, 22mm and 24mm.
All of Holbein’s spring bars are fantastic and I’ve bought them several times. Unfortunately, this time around they don’t appear to fit the lug holes of my Seiko Marinemaster; it seems the flanges of the bars are too thick to seat properly like the factory Seiko bars do. I’ll hold onto them and hopefully find myself with a watch in the collection one day that can make use of them.
These curved spring bars are great for some watches where the lug holes are too close to the case leaving very little room for some straps to use. Thank goodness for curved spring bars so you can change your straps and enjoy your watches more.
I got these spring bars, fat boys, for NATO straps. To give a bit of strength. Have been absolutely perfect in that regard. Highly recommended. I should have bought 40 instead of 20 of them.
