Launched in 1980 and discontinued in 1988, the production run of reference 16570 is remarkably shorter than that of its predecessor ref. 1675 (1959-1980), with a consequent increased rarity.

The present example is offered complete of its original accessories, most notably presenting the sticker with the case number on the green document holder, but its main feature is the superior “spider” dial. A form of aging (akin to topicalization), the spider effect comes from the glossy zapon finish cracking with age and assuming the look of a spiderweb when light hits it at the right angle. The effect can acquire different forms, with the “mesh” being more or less tight. The less tight, the more spiderweb-like the dial looks and thus the more attractive it is. The present specimen distinguishes itself for a superb, textbook example of “spidering”: with large plaques featuring intact glossy finish. It truly looks like a real spiderweb was placed upon it. It is not an overstatement to say the present watch is one of the most attractive examples of spider dial 16570.
