Collectors value this reference due to specific military-grade modifications that distinguish it from standard civilian models, including fixed lug bars for NATO straps, a circled \"T\" on the dial indicating tritium luminescence, and oversized sword hands for improved legibility. The 60-minute graduated bezel and the caliber 1520 movement are also defining technical characteristics. Due to limited production runs and high attrition rates during active service, authentic examples are rare. On the secondary market, prices typically occupy the mid-to-high six-figure range depending on provenance and original component integrity. A notable production variant is the \"double reference\" 5513/5517, which features specific case back engravings and unique specifications requested by the Royal Navy.", "score": 199}]}
