Watch Band End Links Won't Fit? Troubleshoot & Fix Guide

One of the most popular collection of STRAPCODE is the MiLTAT curved solid endlink bracelets, tailor made for selected SEIKO models. STRAPCODE have lots of fans around the world, we discovered nearly half of them are SEIKO watches lovers as well. Customers who bought their Seiko watches from all over the world. This time, we are going to explore why once in a while, their SEIKO cannot fit on our curved solid endlink. And of course, we will show you how to fix it at the end.

Thank you for the volunteers: Anthony, Barrett, Benjamin, Clayton and Desmond. 5 of our customers participated in our research of their Seiko SKX007 & SKX009 which supposedly sharing the same watch case. Will MiLTAT curved solid endlink bracelets fit them all?

...... Findings in the research

Rigid Material

Both bracelet and watch case are made of extremely rigid and hard material – stainless steel, there is no flexibility at all. Other common watch band materials such as rubber, silicone or leather do have some elasticity at least but definitely not for stainless steel. 

MiLTAT Bracelets Standard

Every single watch band link of MiLTAT is individually milled by machine. Then the components are linked to one another after assembly. MiLTAT target to meet particularly tight tolerances, aimed the design of perfect fit with nearly no buffer space. Therefore MiLTAT using the same manufacturing plants to produce the specific models. The well-known bracelets having curved solid endlink from MiLTAT are being scaled up to thicker and heftier. This is not difficult to understand why it cannot be probably fitted when facing a slightly high tolerances watch case.

Solutions

If you are facing the same problem, try the followings

  1. Pay extra attention when locating the spring bar
  2. Use your spring bar tool to grab the tip end of the bar and guide it to the case’s hole
  3. Reverse the pieces you have installed, try again with the left side turn to the right
  4. Try another spring bar or use a thinner spring bar, you just need some buffer space
  5. Email us with your problem, according to your situation we will arrange another right pair of spring bars for you

According to the above table, the vast majority of the customers can easily fit the bracelets to their SKX007 J/K and SKX009 J/K watches. Rarely happens here, two special cases was found : one side of SKX007J case from Anthony cannot be installed to the Super-O Boyer bracelet. Case two: one side of SKX009K case from Clayton cannot be installed to the MiLTAT Retro Shaver bracelet. 

The results waken us that the lug holes on some watch case may have a very very tiny difference. This may be not sized exactly the same or exhibit slight un-alignment that cannot be distinguished by naked eyes.

This can be understood because most of the manufacturing process get involve many processes, tolerances seem cannot be avoided.

Manufactured Tolerances

Watch case are obtained by methods of comprising steps of forging press, cutting, milling, drilling, polishing and assembly. There involved many steps we have not listed in here. The more steps leading to completion, the more manufacturing tolerances may be affected.

  1. Processing of cutting, milling, drilling or polishing
  2. Tolerances in volume under the combined action of heat and pressure
  3. The over and over usage affect the accuracy of tooling
  4. Different manufacturing plants
  5. Processed by different production machines, operated by different workers
  6. Minor differences between production lots cannot be avoided
