Estas hablando dos idiomas diferentes, el 1460M es el modelor de Rolex Submariner no date, el perfeto y limpio en sus lineas que te gusta. Pero hablar de 5512 es hablar de calibres...que es otro tema, te pongo un link muy util para tu futuro Submariner http://www.antiqueweb.com/articles/antiquewatches.html
Reference 14060 was introduced in 1989, concurrently with the new Submariner Date 16610, with the new caliber 3000. This watch was produced for 10 years, from 1989 through 1999. It introduced the white gold surrounds to the hour markers, sapphire crystal, and new fast-beat 28,800 BPH movement. The difference between the caliber 3000 as used in the non-date reference 14060 versus the caliber 3135 used in the 16610 Submariner Date is, obviously the lack of date complication and the absence of C.O.S.C. certification.
Finally, the reference 14060M, marks the last meaningful upgrade to the Submariner line. The 14060M was introduced to replace the 14060. The meaningful difference being an improved caliber 3130, which features a balance bridge for increased shock protection and improved operating rate (i.e.: better timekeeping) and improved winding system.
In 2003 or so, reference 16610LV was introduced, but has only cosmetic changes to the Submariner Date -- a green bezel and a "maxi dial" which has larger hour markers.
