Value proposition: Compared to some Rolex Day-Date models, the Tudor offers a similar look and feel (especially in the bi-metal version) at a more attainable price. For someone wanting day-and-date in two-tone, it’s often a serious contender. 

Rarity / availability: While not ultra-rare, certain dial variations (linen/mosaic, with or without Roman numerals) are less common, making specific variants more collectible. Condition, box & papers, and originality (especially of bracelet, dial, bezel) all matter. 

Heritage / brand prestige: Tudor’s link to Rolex (both technical and aesthetic lineage) adds prestige. Also, Tudor is strong in the vintage / pre-owned watch community, which supports resale and desirability.

Wearability: It’s not too precious; many owners report the watch works well as a daily driver. It holds up, still looks smart decades after release. This longevity is part of its charm. (From owner forums & listing descriptions)
