Collectors value this reference for its use of the Calibre 15, a variation of the Calibre 12 that features an offset small seconds sub-dial at the 10 o'clock position, creating a distinctive asymmetrical dial layout. The 38.5mm stainless steel case utilizes a front-loading design with integrated lugs and a crown positioned on the left side. The 1553S variant features a silver dial with a single blue chronograph register, while the 1553N features a blue dial. On the secondary market, these watches typically trade between $4,000 and $7,000 depending on condition and original components. A notable production detail is the \"tool 107\" engraving on the caseback, indicating the specific tension ring system required for servicing the water-resistant assembly.", "score": 199}]}
