A Blog to Watch

Sinn 900 DIAPAL

Owners praise the Sinn 900 DIAPAL for its 24-hour GMT hand and Sinn's proprietary technologies including the TEGIMENT case, AR dehumidification, and copper phosphate tablet. The internal rotating bezel is noted as very easy to turn but prone to being knocked out of position, making it unreliable for elapsed time. Some owners find the large dial contributes to an illusion of a bigger watch. On balance, owners value the Sinn 900 DIAPAL for its advanced proprietary technologies and GMT functionality.
