There are several features about this reference 1680 submariner that are worth discussion. As an example produced in yellow gold this watch departs from the standard steel production. Not only this, the bezel insert, brown in colour, are particularly scarce. The most noteworthy feature however is the dial, now sienna, it was once much darker in colour having changed over time. The dial is also what is, somewhat comically, known as a nipple dial to collectors. This of course refers to the rounded dot indexes that stand proud of the dial.  This type of dial was only made for a limited time during the late 60s and early 70s.
