The Importance Of Curved Watch Band Spring Bars

A watch and watch band is linked by two spring bars. The standard spring bars that can be found on the market are usually in straight form. However, according to design criteria, some watch cases may be designed with a tiny little end to hold the spring bars. The space between watch and watch band will then be narrowed down. In such cases, straight spring bars may not be firmly fixed or cannot be inserted. The intelligent designers will change straight one to a pair of curved spring bars to increase the space between spring bars and the watch case. IWC Portuguese IW503502 is one of the watches having this situation, but no worries, STRAPCODE got you a solution.

As much as we would like to design and provide curved end fitted bracelets for as many watch models as possible, its certain that not all models and requests can be fulfilled. However, when it comes to spring bars, whether you are talking about twenty dollar toy watch, or a luxurious watch that’s worth tens and thousands of dollars, spring bars are the essential tiny pieces of metal that is the main component holding and keeping your watch and strap together.

For as long as I can remember, even before having serious interest in watches, the words “Spring bars”, was like one of the very first watch terminology I came across. Through time, you’ll come to the realization of the importance of spring bars. The basic idea of a spring bar is a mini-size telescope tube that are held together by two pins inside the lug holes of your watch case.

There will be times where you would feel thankful and satisfied because the spring bars used helped with the fitting problem with your new watch/bracelet. Then of course, there will be times where you will feel frustrated and fed up to the point after countless trial and error with different spring bars, and still unable to get that perfect fit with fitting the watch band onto your watch.

Sometimes, all it takes are minor adjustments, or even a slight bend on a curve of a spring bar, and your fitting problem with your new bracelet onto your watch can be solved.

Of course, there wouldn’t be a problem if there was curved end fitted bracelets for every watch on the market, but you know that’s more than likely it would not happen.

With the use of curved spring bars, especially when used on leather strap, it certainly rectifies the fitting problem, by adjusting and bending the curve on the spring bar to fit as closely as possible to the watch case.

It’s convenient for those who have several watches with the same lug width size. You can now attach the strap on more than one of your watches, just by using a different set of spring bars.

In the course of watch development over time, not only the watch cases have changed, spare parts like spring bars have also changed and adjusted, in order to accommodate and be able to be used on newer watch models.

Spring bars should be cared for and attended to more often than it should. They maybe small, cheap, replaceable, which make it easily forgotten as to how important their roles are. Spring bars are in fact the key essential component that is keeping your watch and watch strap together.
