I'm a sales advisor, so taking JET has helped improve the service I can offer my customers. When I began at F Hinds, my product knowledge was very limited. I was particularly intimidated when it came to selling the more sporty, technical watch styles. JET further helped to expand my knowledge of their mechanics and history, all very interesting. So, I’ve replaced the fear with a new-found love and fascination for watches. I’m now known for fuelling both passion and commitment into my window.

When first pushed to do JET, I was a little hesitant, doubting whether I had the skills to succeed. When I began my first assignment I admit that I felt somewhat daunted and inadequate. However, my tutor was incredibly supportive and gave me lots of positive feedback, which helped to build my confidence. This, in turn, helped me begin to really enjoy my studies. The NAJ training website and the reading materials were all very useful research tools.

I cannot begin to describe how thrilled I am! I’m so glad I had the opportunity to take this course, and so grateful for all the support and encouragement I received from those around me.
