Watches for trade (Los Angeles)

Different colors.
Many wind.
A few use batteries.
I am looking for a video game system (modded may be even better), small carbon fiber men's bike, electric scooter, high end cellular phone or what do you have? The value of each of these are around three hundred and fifty dollars, if you looked! I may trade one or more depending on what you had.
I would also a combination of consider cash and product trade.
