Tom Nielson

Tom's love for watches started when his grandfather gifted him his Rolex watch when he turned 18! Being a teenager it was a big deal for him. Later when he got his first job he bought Fossil Palm Pilot back in 2003 which was a smartwatch. Since then smartwatches have come a long way and so is Tom's love for them. His experience with watches inspired him to start Wearholic and share his knowledge of wearables including watches, smartwatches, smart glasses, & smart clothing.
