Search Dive Computer/Watch SEARCH Dive computer with color display and Bühlmann e.g. OSTC, G2, iX3M

As a backup computer, look for a used (well-preserved) dive computer, e.g.

Heinrichs Weikamp OSTC (all models)
Scubapro G2
Ratio iX3M / iX3M2 (all models)
Shearwater Peregrine / Perdix / Petrel
Mares ICON HD / Genius / Quad CI
...???

A color display is important to me, adjustable GF's according to Bühlmann, gas change (at least 3 gases Nitrox).

I don't want a Aqualung i330R (which locks itself after a deco violation) or funny computers with an RGBM model.

The condition should be at least usable, I would be happy to receive an offer with a realistic asking price, information on age/TG/condition and two/three detail photos of the display. Either I like to pick up the device personally in the Ruhr area/Lower Rhine region and pay in cash, otherwise PayPal or bank transfer possible.
