My Data Bank Watch DBC310-1 was exactly what I ordered and received. The old Databank 150 started to fail after about 12 years of service. I ordered the new Databank 300 to replace the 150 & it is the Exact same watch with 2x the memory. I didn't have to read the instruction book because it operates the same as old watch. I was lucky, I was able to retrieve my list of phone numbers from the old watch, and put them on the new watch. One more thing, I would like to see Casio Data Bank with Solar power and Atomic time keeping.I received the new watch in a timely fashion. Pleased with the product and service. thanks
