Don't miss the next drop
Lemon yellow is a lot of color for a 20mm Omega, and on a case this small it does most of the talking. It is a vintage Omega Ladymatic in stainless steel, signed with the Omega symbol and name above center and Ladymatic in flowing script below. Narrow applied batons mark the hours, with a doubled baton at 12, and there is no date window to break up the yellow. Age has left a fine mottling across the surface and a web of faint pale lines, most visible below center.
A slender seconds hand sweeps the whole face, and the reference stamped inside the caseback, 11000 SC-61, marks it with SC for center seconds. On a dial this size, a central seconds hand is the quickest way to see that the watch is running, and it keeps a little motion going across the yellow.
That movement is Omega’s caliber 455, with its number stamped on the bridge. Omega developed it in the early 1950s specifically for women’s watches, and it measures 16mm across, narrower than a US dime. Into that circle went 17 jewels, the center seconds train and a shock-protection system.
The name on the dial was a compact piece of product description. When Omega introduced the Ladymatic in 1955, the word told buyers they were looking at a self-winding watch made for women, and the 455 was the movement inside. The name held up well enough to be worth reviving: Omega brought it back in 2010 for an entirely new collection, 55 years after the first.
The outside of the caseback adds a second name. It is stamped Seamaster above the line’s sea horse emblem, so the dial names the Ladymatic while the back belongs to the Seamaster: two Omega lines on one small steel watch.
It is small without being slight. The case measures 20mm across and 25mm from lug to lug, with straight faceted lugs that angle downward and a smooth bezel, and the steel shows fine scuffs from use. The crown carries the Omega symbol. We’d keep it on the black leather strap, where the lemon reads at its brightest. Seen from the side, a tall domed crystal rises well above the bezel and puts a curved lens over all that yellow.
