Rolex Oyster Precion 6424, black dial, manual winding, all stainless steel case, ca 1962, with its original oyster rivet bracelet 7206 end link #75 20mm. The bracelet alone in good condition costs us US$ 1,000. You can find this model in ebay but they have no bracelet, because they sell the bracelet separately. This is the most wanted, most desirable and very highly collectible Rolex Oyster Precision, the only Precision model with 20mm bracelet and 36mm size!!!! if you had this 6424, you would not need to collect any other Precision model. This one is enough. Enough!!
