A stainless-steel automatic diver's Omega Seamaster of the 1970s is estimated £80-£120. Omega lost ground to Rolex in that decade by turning out some really ugly watches. But this one is handsome.
Ladies' watches are relatively cheap because of competition from jewellery. Twelve 20th-century watches, 10 of them ladies', are lotted together at £250-£350.
It is a good week for collectables at Bonhams, where studio glass is likely to show further recovery in Friday's decorative arts sale (11am). It will be a long time before Daum regains its precarious price pinnacle of five years ago, when a slender cloudy blue and green wheel-carved ewer might have fetched as much as £12,000, instead of the £6,500-£8,500 estimated in this sale.
Lalique, another volatile market, is becoming more confident. In the same sale, there are 50 lots, with plenty of quintessential vases and bowls under £500. Avoid chips.
A third Bonhams sale focuses on the firm's new-found market for mirrors on Tuesday (2pm). There are a dozen Victorian gilt overmantel mirrors. One is modestly estimated £100-150.
