The mechanical chronograph still offers some of the most utility of all available watch complications — you can time laps, or that pot boiling on the stove, or whatever else you need, all without having to result to multi-tasking on your phone. Swiss models from the mid-20th century are readily abundant and many developed a beautiful patina by now. Though they can be pricey to service, if you can snag one from a reputable dealer, these watches can provide decades of use and enjoyment.
Angelus 215

What we like: Featuring a relatively rare 45-minute totalizer as well as a running seconds register and telemeter scale, this 2-register chronograph from famed Swisss maker Angelus is a true beauty. Though the dial features some speckling and patination, we believe it only adds more character to this gorgeous timepiece.
From the seller: This example is overall very good. The case is clean with just superficial scratches. May have received a light polish in the past. Movement runs well keeping accurate time, chronograph works as it should. Dial shows age with some blemishes seen throughout.
Gallet Dual-Register

What we like: Finding a vintage chronograph with a 45-minute totalizer as well as both a telemeter and a tachymeter scale is a tough proposition, but this elegant offering from Gallet managed to incorporate all these features, and to do it without crowding the watch. With its attractive, patinated dial and blue steeled-hand set, this is a timeless design that has aged incredibly well.
From the seller: Watch is in overall excellent condition, case shows marks on the lugs (particularly the lower right) consistent with use and strap changes. Silver Sunburst Multi-Scale Dial is in near flawless condition with crisp printing in red, blue, and black. Blue Steel handset in excellent condition.
