Which maker turns up most often?

Omega, by a wide margin. The name is in over a third of the titles in this category, and the Seamaster accounts for a large slice of those. Geneve, De Ville, Constellation, Dynamic, Chronostop and Speedmaster titles fill out the rest. Longines, Smiths, Bulova, Tudor and Rolex follow, then a long tail of smaller Swiss names.

What period do these mostly come from?

The 1950s and 1960s together account for most of the dated listings, with the 1940s and 1930s behind them. Earlier pieces thin out fast. The 1920s and 1910s appear only in small numbers, and the earliest dated things in the archive include a 1905 silver trench watch, a 1910 Wilsdorf & Davis ladies' watch made before the Rolex name existed, and a 1916 Omega in a cushion case.

Why is a 1970s watch filed under the 1960s?

The decade field is a bucket, not a date. Titles naming 1972, 1973, 1974, 1978 and 1979 all sit in the 1960s bucket, and only six listings carry the "Later Than 1960" label. Two watches are filed as "19th Century" and one as "Victorian" despite being twentieth-century pieces. Where a title states a year, that's the more reliable figure.

Are military wristwatches a big part of this?

A small seam, but a distinct one. Around forty-eight titles say military and about twenty say British military. The Dirty Dozen WWW watches appear sixteen times, and other issue types include ATP, RAF 6B/159, Wehrmacht and Kriegsmarine pieces, US ORD DEPT markings and a Vixa Type 20 French Air Force chronograph.

How large are the cases?

Modest by modern habits. Where a size is quoted it tends to fall between 26mm and 36mm. The largest measured piece in the archive is a Longines described as oversized at 37.5mm. Many listings give no measurement at all.

Do ladies' watches appear in this category?

Yes, though in far smaller numbers than gents' watches. Dress and cocktail watches make up a small minority of listings. The diamond-set platinum and white gold cocktail watches sit at the top of the range, alongside Rolex sports models and Heuer and Breitling chronographs.
