Size chart for bracelets
To determine your strap/bracelet length, you can either measure your wrist circumference and determine your bracelet length in the table or use our templates, which you can download below.

Instructions: Print out the document and make sure that no page scaling is preset. Cut out the template along the red dotted line. Place the watch on your wrist and pull the strap through the cut slit. Make sure that the template is not too tight on your wrist and that you have a little space between your fingers.
Please note that leather underbands result in a longer strap length.

AQUASPHERE Matte Black
The bezel and dial are deliberately finished in matt black, underscoring the watch’s functional tool-watch character. The interplay of polished, brushed and matt surfaces gives the case visual depth and rewards closer inspection.

Three strap options
An FKM rubber strap with a stainless steel folding clasp is available as an alternative. The hard-wearing material is resistant to water, perspiration and heat and is easy to clean. The folding clasp holds the watch securely, while quick-release spring bars allow the strap to be changed without tools. The rubber strap is available in two lengths, M and L.
The stainless steel bracelet combines robust construction with a classic look. It can also be changed without tools thanks to its quick-release mechanism. A tool-free micro-adjustment integrated into the clasp makes it easy to accommodate changes in wrist circumference caused by heat or physical activity.
