I am attempting to put new batteries (CR2025 and SR6265SW) in my Stauer Colossus Hybrid. I need a diagram to reassemble the watch. Is an internal assemble of the watch available?

SOURCE: my stauer atomic signal watch won't set correct time

Take a look at http://www.stauer.com/pdf/17468.pdf
I see that this watch gets it's time signal from Boulder, Colorado so it will only work properly in North America. Perhaps they also do models for the European market - if so I would expect them to work in the same fashion so the manual should still be relevant.

SOURCE: How do I remove a link from the Stauer Colossus Hybrid Chronograph

Removing a link from the wrist band of the Stauer Colossus watch is a task that requires some mechanical talent. The links are held together with pins. These pins need to be pushed out. I strongly recommend the purchase of a "Watch Band Link Pin Remover" (got mine on eBay for $7). Prepared with this tool, the steps are as follows.

a) Separate the wrist band at the position where the strap and latch are held together. Careful! This pin is spring loaded.
b) The links that can be removed are marked with an arrow on the interior side. The pin should be removed in the direction indicated by the arrow.
c) With the previously mentioned tool you will be able to perform the hardest part, namely push out the pin by 3/16". In the image below note how the pushed out pin goes into the groove of the tool.

d) Use a small screwdriver or a punch with diameter of less than 0.07" (or 1.8 mm) in order to push out the pin completely (see second picture).
The push pin of the tool can be reversed which is helpful for re-assembly. I recommend smoothing the one end of the pin with a small file or sandpaper. This way the pin enters easily into the hole of the lower section. Else you run the danger of bending the link if the pin is not correctly positioned and you apply too much force.
