Praesidus A-11 Spec 2 Ameriquartz

Owners praise the Praesidus A-11 Spec 2 Ameriquartz as a sturdy, versatile tool watch at $215 USD, noting its precise Ameriquartz movement. However, some owners report unpolished lugs, random timekeeping errors ranging from 5-15 minutes off, premature battery death, and difficulties with battery replacements and customer service. The canvas strap is also noted as being very long, and the crystal is sapphire-coated K1 mineral. On balance, owners find the Praesidus A-11 Spec 2 Ameriquartz a capable daily beater despite these specific concerns.
