What can I do for you ?   I would like to buy two exquisite watches for me and my girlfriend .   We have many pairs for couples . Look at this counter .   This pair is Rolex , right ?   You have a very good taste , this pair is the latest product .   What function does this watch have ?   Both of them are luminous with a time reminder function . They don't need battery , because they can absorb energy from the sun .   Sounds good .   In addition , they are waterproof and shockproof .
