Broken strap. My watch strap broke and i lost the pin and a stainless steele spacer, i would really like your advise on how i can get hold of these spares or where i could get my watch fixed.I look forward to hearing from you.

You should find a couple of pins buried away at the watch side of the strap. These are spring loaded and hold the strap in place using tension.
Simply put the watch face down on something soft, the clips should be visible at the corners of the strap and take some needle nose pliers or small flat screwdriver and push inward from one of the outer edges. This will squash the spring and enable you to remove the strap.

There are typically small pins that hold the band together. There is a special tool to use on metal watches that can be bought

Some sprint bars need to be curved, get them in stainless steel.
You need to know the MM size of the spring bar, yu may find that on the strap if its the original strap.
Search for - SWISS REIMAGINED Curved Stainless Steel Spring Bar Pins.
For a box of mixed size straight spring bars look for - Ritche Professional 360pc Watch Band Stainless Steel Link Pins.
Pick up the spring bar tool as well. Amazon sells all of it.

Purchase a new strap for the watch like http://www.amazon.com/Wenger-20mm-Stainless-Steel-Metal/dp/B004PVZZV4%3FSubscriptionId%3DAKIAJMYZ4A7DX4X4RQ3A%26tag%3Damazon-buzz-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB004PVZZV4

The caps are just for decoration. They dont cover anything. To remove the strap, you have to release the spring loaded pins from the underside of the band. There are two on both ends. Reuse the pins with the stainless band but be careful not to have a pin go into the wrong hole because they can't be removed without breaking them!

sounds like a broken spring bar.They break all the time and can be replaced by any good jewellery store while you wait.

mcdevito75 here, Aren"t the spring bars (pins) built into Invictas Strap?? Look on the back of the Strap real close to where ot attches to the watch, see a little tab you can move with your fimger, this tab should compress the spring bar (pin) and allow you to remove the strap.

I had exactly the same problem with exactly the same model watch, and it happened to me twice. The AQ-160 is the important part of the model number as far as replacement parts are concerned. The first time, I took it to the shop where I bought the watch, and they replaced the band, but it cost me $50. The second time, I looked up the Web for the master agent for Casio in Australia, and they said I could buy the end piece, not the whole band, for $6. I found I could replace it quite easily myself by using a drawing pin to remove the spring pin that holds it together. A bit fiddly to reassemble but not too bad. In fact, I didn't wait for the new part to arrive, just used the unbroken end of the old band. So now I have a repaired band plus the old band and a new end piece, in case it ever happens again.

I really like this watch, but it is a pity the bands are so weak.

The band has pins in it which can be removed by tapping them
