4. Strap material
Leather straps will make your watch look more showy. A Stainless steel strap, even if it is the same size as a leather strap, will look bigger and heavier because of the nature of the metal. If you have a thin wrist, this is an important piece of reference information.
Stainless steel straps are usually preferred by men with thicker wrists because they appear to have a larger watch appearance. If you have a thin wrist and want a stainless steel strap, then you can combine the features described above and choose a smaller scale metal strap, but it still depends on personal preference.
5. Watch details
Finally, knowing the size of the components on your watch is not the least important thing.
If you have a 38mm to 40mm watch with huge numbers; the buttons on the body are too big or too small, then it will look out of place. On the other hand, if you have a 9mm thick watch with a 46mm diameter case and a thin hour hand, it will also look a little out of place.
In the end, all these verified data are also just for your reference, not that it’s a certainty and has to be that way. It all comes down to you personally.
