Tiktox had a limited supply of this model. Unfortunately, at the time I noticed it, they were already sold out. I did some more searches, but the price was a bit high for me. The GW-3000B retails for €249.- ($304 - £211), which makes it a watch moving to the more expensive segment.
Tiktox website for something completely different. Suddenly I saw Tiktox had a limited supply of the GW-3000B back in stock for the very sharp price of £154 (€182, $222). It was now or never, so I shoot an e-mail to Keith at Tiktox. Of course I was a bit impatient, so I called Keith the next morning. He had just seen my mail and was about to respond. Long story short, I got this watch a 3 working days later (we had an extra holiday and it had to travel over the weekend). Needless to say I was very excited to see this watch finally in real.
the manual for module 5121 from Casio’s manual archive. It is only a 6 A4 pages and it reads much easier than the small pages of the manual provided with the watch.
