Classic Hamilton Bolton model 6186 tank-style wristwatch in very good working condition.

This is the desirable 23mm case size, matching known examples of the model, with a gold-tone rectangular case and clean silver dial. Features applied Arabic numerals and a sub-seconds dial at 6 o’clock that completes a full rotation every minute.

A fresh battery has just been installed and the watch is running smoothly.

Case back is marked Hamilton Watch Co. with “Case Made in Japan,” consistent with late production quartz Hamilton models. The watch is fitted with a brown leather strap marked Canada.

Condition:

* Fully functional with new battery

* Dial shows light wear/patina around some numerals (see photos)

* Case has minor surface wear consistent with age

* Crystal appears clean

* Strap shows moderate wear but remains usable

Please review all photos for exact condition.

Era Estimate:

Likely produced in the late 1980s to early 1990s, based on the quartz movement architecture, “Case Made in Japan” marking, and the Bolton tank reissue styling that Hamilton offered during this transitional period. The use of a sub-seconds register in a quartz watch is a distinctive design carryover from earlier mechanical styles.
