Types of watches with black leatherThe most common types of watches that have black leather straps are dress watches and chrono watches. Dress watches typically have lines instead of numbers on the faceplate and they are recommended to be worn to black tie or semi-formal events. They can dress up an outfit instantly and they'll make you look polished.
Chronograph watches tend to run bigger, sometimes they might have a wider black leather strap, and they're meant for less formal situations than the dress watches. However, they can go great with different kinds of casual and semi-formal ensembles.
Matching black leather Matching the leather to the rest of your outfit is the way to go. You'll want to make sure that when you're wearing a black leather belt, you're not clashing by wearing a brown coloured leather watch with it. A smooth formal look will have very similar leather hues and textures, and they'll match with the rest of the accessories. So for example, if you'll be wearing crocodile-style leather black shoes, your watch will preferably have a crocodile embossed look. If you're wearing a smooth, unstitched leather watch strap, try to match it up with other similar plain black leather accessories to finish your look.
Mixing metalsThe two most common types of metal faceplate colours are silver and gold. However, a third option which is very popular and tends to clash less than the previous two with certain leathers and with other metals is a black matte finish. This metal tone can be achieved either by an anodized version of different kinds of metals. The most common one used is stainless steel. Gold watches and silver watches are the most common metal hues used in jewelry. However, if you're a guy who wears one metal more than the other, stick to your metal colour to achieve uniformity.
Caring for leather accessoriesBlack leather is a material which can be very durable if it's taken care of properly. It can last for many years and it could become your signature style accessory. There isn't much care involved in leather, although you do need to keep it away from water and sweat. Leather can be very easily damaged when it comes in contact with water and it's not dried immediately. Leave your black leather strap watch at home when you're going out for a run or hitting the gym. By doing this, you'll make sure that your leather strap will last a long time.
If you want to make it last even longer, make sure it doesn't get too grimy or that it starts cracking. You can easily use leather soap or conditioner once you start to see creases on the surface, but if becomes necessary, the leather strap can be replaced to continue using your watch.
