What is Hidden Lug Watch? And the Demo by Universal lug Watch bands

If you’re one of the adventure spirits who just can’t settle having the same watch band for a lifetime of your favorite watch, then you’ve probably come to the point where you wondered how to pick the right watch straps to change the stock one. Since the most of the watches have the curved case, most of the stock watch bands come with the curved end links to fill in the gaps between the watch case and the watch band. 

Seiko Prospex Quartz Tuna S23626 is one of  the watch with a "hidden lug" lies beneath the watch case, on left : Super-J Louis watch band SS221820BBK020S , Right : Hexad Watch Band SS201803BBK042S

But, when it comes to curved end links, in the last few years many people prefer to buy watches with the HIDDEN LUGS, whose watch band's 'end links' are hidden beneath their case. This not only hides the gap between the watch and the watch bracelet but gives you plenty of options when it comes to combining your watch with custom watch strap bands.

These, so called straight lug watches, or watches with the hidden lug have the option which allows you to perfectly match them even with straight end link watch bands. That means that there’s no gap left between the watch case and the watch band or at least it isn't visible from the outside, no matter which type of watch bands you choose.

Therefore, the 'end link' is as firm as the one with the stock watch bands. That means you can pair these watches with basically any watch bands with straight end links and need only to match the width of the bracelet with the one on your watch. Most common lug size can be found are in even numbers such as 18mm, 20mm, 22mm and 24mm however there are odds size as well, watches may be found at Grand Seiko Boutique Limited Edition SBGJ235 Hi-Beat 36000 GMT and Seiko Prospex Diver SLA017, both have 19mm lug.

That not only minimizes the amount of work you need to put in to swap the watch bands – but it also means that you don't need to worry about the fit anymore as you would with curved end links.  Look at it this way - this is like owning a watch with both curved and straight end link option, with the possibility of making your watch fit any outfit by matching it with the desired strap band and without losing anything on the aesthetic side.  Take a closer look at our pictures to see some of the watches from Seiko’s Marinemaster and Baby Tuna series showcased with some of the best watch straps with straight end links. Most of these watchbands come in standard width options so you only need to know your watch lug width.
