The Sears Tower 23 is a 35mm SLR sold in the United States under the Tower house brand of Sears, Roebuck and Co. and manufactured by Asahi Optical. It was positioned as an affordable enthusiast SLR at the time of retail, and today it is collected as part of the Asahi Pentax rebadge family.

Hammer prices at recent UK auction have spanned roughly £70 to £200, with a median of about £94 across the small number of recorded sales — these are wholesale saleroom results, not retail asking prices. As of 2026 the camera trades thinly, and value is strongly condition-sensitive: cosmetically clean, working bodies sit at the upper end of that range, while untested or cosmetically tired examples sell for closer to £70. Because recorded volume is low, a single clean sale can move where a Tower 23 sells for in a given month.
