There are many factors that will come into play when deciding on one of the two different accoutrements.
Why Leather?
Many people are allergic to the metal that most watches are made from, some people are even allergic to gold and silver, still fewer people can only wear platinum due to the inert quality of the metal. Rather than forking over the amount of money it would take in order to purchase a platinum wrist band, these types of people are more than likely to opt for the leather band, and probably the band that goes under the watch itself holding that metal away from the skin too. There are a plethora of different leather styles that can go with just about any style of watch you can imagine, from a slim, narrow leather band for the elegant slim line watches to thick impressive looking bands for the large multi-function watches.
Why Metal?
Some may even opt for leather for their dive watches, however most would probably opt for the metal band because of the imperviousness to water and the ease of cleaning and drying. There are many styles of metal watch bands, from the stretch type to a clasp type. There are narrow bands as well as wide ones. Your best bet is to take your watch in and hold it up to the different types of bands to see which one you prefer. Maybe try a watch on that already has that type of band attached. This is an item that will stay with your watch for a long period and you want to make sure you make a well considered decision.
