This is an early production of a Hamilton Whitman with a Illinois movement and dial up for sale. Roughly 1650 of these Illinois "W" 980 series movements were made this one with a fairly low serial number of W181. The 17 jewel 14/0 size manual hand winding movement has been serviced and kept good time over a 24 hour period. The sterling silver applied gold numeral dial looks sharp and the case measures approximately 22mm wide (excluding the crown) x 38mm in overall length. A new glass crystal and brand new genuine lizard straps are included with this wonderful timepiece. The back case is marked: Wadsworth, 10K Goldfilled, H737280. There is some wear on the back case corners and edge on the crown side.
