The 5711/1A features a three part case construction with sapphire display back to reveal the caliber 315 SC. With center seconds, the 5711/1A immediately differentiates itself from its inspiration, the 3700/1A. Furthermore, the clasp construction of the 5711/1A is a double folding clasp as opposed to the single fold of the reference 3700/1.
