Watches Women Holzkern Cirrus (Zebrawood/Nacre) Latin for ringlet or a curling lock of hair, a thin, wispy “cirrus” cloud formation is made of ice crystals formed in very cold air at an altitude of about 8,000 to 12,000 meters. One can easily observe the direction of the wind in the upper atmosphere as it creates tails or streamers when it blows through the cirrus clouds. With golden stainless steel and white mother of pearl (nacre), you will find a daily reminder of this natural phenomenon during a glorious sunset right on your wrist.
