I just got a used watch from my father in Spain. it is Lotus alarm chronograph (satainless steel) and I don't know how to set up the time. it has two push buttons on the left and on the right there is a push button on top, a push button on the middle that can be pulled out, and a wheel on the bottom right that can also be pulled out. I looked on the internet but I see nothing (extrange). the brand logo says Lotus with a little arrow on top pointing to the left.
