The clock has a genuine leather strap which passes under the Geghäuse and therefore it is very comfortable to wear because the cold metal is not directly on the skin. I am allergic to some metal clocks and so I need me so worry. The clock I wear all day at work and it does not disturb or slips unangenehm- for me just the right size. The bracelet is patterned in itself (marked), so what you do not see in the pictures. If the strap is broken you have to time it but cut it because actual riveted but that is then not care because it anyway is broken if you change it. The battery change should nevertheless be possible, you can cover the Open- the bracelet leaves enough room on the housing base. One needs to be sent a little maybe. Previously, I had to change the battery is not and can not therefore speak from personal experience. This simple but beautiful design appealed to me immediately and the cheap price (I paid about 18) did the rest, I like it very well.
