Stainless Steel Spring Bars - 2.5mm Heavy Duty
2.5mm spring bars for Seiko dive watches and similar tool watches.
- Price
- $12
Minimum order: Orders must total at least $18 before checkout.
Heavy duty 2.5mm spring bars are typically used in Seiko dive watches and other tool watches designed with larger lug holes. The thicker diameter is intended to handle heavier cases and straps, offering a more secure fit under demanding conditions.
Material & feel
Solid 316L stainless steel spring bars with a straight profile and double-flange design. Each bar has a 2.5mm shaft diameter and a 0.8mm tip diameter.
Sizing & fit help
Choose the spring bar size that matches your watch’s lug width. The 2.5mm diameter is not standard and will not fit most watches, but is required for cases and straps designed for thicker spring bars.

High quality and sturdy spring bars. Firm spring tension too, they hold securely giving peace of mind. Worth spending the money on, these are what keep your watch from hitting the ground
Great spring bars for even better price.
These fit the bill. I purchased a Bonetto Cinturini Italian Rubber watch band. The bands holes for spring bars were a touch sloppy and looked like they could handle the 2.5 mm spring bars. It was a tight fit, but worked really well!
I needed some 19mm spring bars for a new Oris diver. Holben's has a great selection of quality spring bars and the size I needed. Maybe bought a strap or 2 as well ;-)
These curved spring bars are strong, well made, and provide an excellent fit. The curved shape allows the strap to sit closer to the watch case for a cleaner, more finished appearance. The double-flange design also makes installation and removal easy. A simple and worthwhile upgrade for improving the overall fit of a watch strap.
The bars worked great and helped me out of a jam. Time will tell on the longevity, that said they seem well made and again worked for my purposes
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.
Thanks for the feedback and for the continued support. These 2.5mm bars have thicker shoulders, which can be a tight fit on some Seiko models like the Marinemaster, where the lug holes and shoulder clearance are more specific to their OEM bars. That’s useful to have noted.
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.
Great quality, sturdy spring bars with firm spring tension. These 21mm spring bars are a perfect match for my Brequet Type XX chronograph. I wish Holben’s carries also quick release spring bars. Thanks Holben's, highly recommended!
Great service. Appreciate the quick shipping.
Thanks for the 20 & 20 mm spring bars that fit & hold well on my watches.
These are very good quality and I have zero worries about trusting my watches to these spring bars
It can be difficult to get decent well made spring bars that don't break easily every time you adjust or change your watch strap. These are the business. They seem solid and well made.
I know when I order from Holben's that the quality will be there. These spring bars are much better & beefier than the stock that came with my watch or anything I could order from the watchmaker. With an 8" wrist I sometimes put too much torque on the skinny spring bars. Also very much appreciated is Holben's easy website and ordering, and the quick shipping. Now to find more things to order from them, which won't be too hard. Thanks Holben's !!
These are great for watches that have too much gap between the lug hole and the case. They bring the strap closer to the case, especially Nato style. Tudor, Steinhart, etc..
Great spring bars. They fit just right.
Thanks
Ordered a variety of spring bars for few watches in my collection. All look great, arrived very quickly and order was accurate. Only ones I have used is the 20 mm curved
Beautiful, nice strong fat spring bars . I'll never loose a watch now. Thanks
Heavy duty. Great for Seiko dive watch

These are amazing in quality! Definitely worth the extra money.
These FAT BOY bars are really nice - just what I needed for my watch. Thanks!
Excellent! brought 2 more. Thanks very much! Fast shipping too! A+++++
