Rare Illinois Sangamo Special Housed in Beautifully Engraved Green Gold Fill Case

This Illinois Grade Sangamo Special Model 13 is truly a rare find. Illinois made a mere thirteen production runs for a total of 11,200 watches between 1923 and 1926. Because of this watch's low production numbers and its exquisite beauty, the demand for it remains high.  It features an unusual size 17 movement making it the perfect compromise between the smaller size 16s and the larger size 18s. Its high-quality 23 jewel railroad grade movement of ruby and sapphires are in raised screw-set jewel settings.  The green gold fill case is fitting to such a high-quality movement, featuring rich floral engravings with a discrete crosshatch background. The green gold fill casts a subtle green hue enhancing the stunning appearance of this rare timepiece.  Its dial is in excellent condition and displays the classic Illinois railroad dial enhanced by a rich and heavy ink saturation that makes the Arabic numerals stand out boldly. Diamond-style hands wonderfully highlight the numerals and amplify the robust presence of this watch.    It is a highly treasured timepiece due to the combination of its rarity and the high demand for the exceptional craftsmanship put into its design, making it a striking showpiece.
