Hi I love my Invicta watches also. My wife is telling me that collection is close to how many shoes she has LOL. You will need a special tool the tool has two adjustable prongs so it will fit a Rolex and any other screw on type watch. Normally they come in a set of watch tools. I would suggest eBay, you can get a kit that not only will open any back on any watch but you will get tools for removing the pins in the band. There is also a unique tool to help you put the spring pin in that holds the band to the watch. One word of caution when searching on eBay look to see where the seller is. If it is China I would find one here in the States. I hope this will help you
Have a great day.

Contact the authorized service center. There is nothing you can do, in this case. Gopakumar Gopalan Google

You should use two extremely small flat head screw drivers to remove links on Invicta polyurethane watch bands. The smaller pens on the polyurethane watch bands have a notched cap (tiny screws) on each end .You must use one screw driver to hold the pen cap (screw) steady and the other screw driver to turn the cap (screw) counter clockwise. You only have to remove one notched cap (screw). These caps (screws) are very small and you should be careful not to lose them. Once you removed the cap (screws) you can use a small screw driver or paper clip to push the pens through the links. You should repeat this til you remove the desired links.

Thank you for contacting FIxYa.<br /> I suggest you take your watch to a reputable local jeweler for sizing. Expect to pay a nominal fee (around $5) for this service. Do not attempt to size your own watch! You may damage or scratch the watch and bracelet. The liability is yours.<br /> If you still decide to do, follow instructions given here:<br /> <a href="http://www.webwatches.co.uk/how_to.htm" target="_blank">http://www.webwatches.co.uk/how_to.htm</a><br /> Best wishes.

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.

Go to the "invicta.com" web site.

Put your cursor over "collections" and select "Instruction manual".

There appears to be only one manual covering all their watches.
