I purchased this piece about 8 years ago and like a beginner collector have had it in a box for about 6 years till today... I was worried I would need to repair it because it had been years since it had seen light. Much to my surprise a quick 10sec charge and click back in business now to zero out and reset. I would highly recommend any citizen time piece for the craftsmanship, durability, style, and amazing respect for customers thank you
