Hamilton Jazzmaster Auto ChronovsLongines MASTER COLLECTION

Owners widely praise the Hamilton Jazzmaster Auto Chrono for its value and dressy yet substantial look. The H-31 or adapted 7753 movement is noted, alongside a 60-hour power reserve. Some owners prefer a 3-6-9 subdial layout or a smaller case size, and the movement's thickness makes it unsuitable for those seeking a slim watch. On balance, owners rate the Hamilton Jazzmaster Auto Chrono highly for its value and refined aesthetic.

Owners and reviewers widely praise the Longines Master Collection for its excellent fit and finish, heritage-inspired design with features like Breguet numerals and leaf hands, and the value it offers, particularly for complications like chronographs and annual calendars. Specific models are noted for their beautiful dial execution, creamy white barleycorn or blue starburst finishes, and practical complications. Some owners find the Master Collection thin and dressy, appreciating its vintage aesthetic. However, drawbacks mentioned include a subdial potentially obscuring numerals, a bracelet lacking micro-adjustments causing fit issues for some, and a case finishing described as homogenous by one owner. The 30m water resistance on annual calendar models is considered light, and the crown and pushers on the moon phase chronograph are described as uninspiring. One owner reported a broken moon phase setting mechanism.
