As a Man, who has a growing number of 'Ladies' timepieces in his collection, I would most certainly say that we can be colorful, wear 'playful' pieces, or wear diamonds if we so choose to without fear of being ridiculed.
Some have stated that a timepiece is one of the few pieces of jewelry that is socially acceptable for a Man to wear and even then, many Men who wear diamonds are said to be 'over compensating' ... I find these views to be ridiculous. It is 2015. Women and Men should be able to wear what they want - period.
I started off owning one ladies timepiece and the number continues to grow, as I felt limited by choices in many Men's collections.
I would say that real men should wear what they want with pride and confidence....I see too many people running to the forums asking if they can pull this off or pull that off... Wristwatches are not gender specific.
I have actually written to some of the major watchmakers with respect to their marketing and have discussed this topic on other forums as well.
