What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Longines CONQUEST HERITAGE CENTRAL POWER RESERVE

The Longines Conquest Heritage Central Power Reserve is widely praised for its beautiful, timeless, 1959-inspired dial and unique central power reserve indicator, with owners considering it a top dress watch in its price segment. Reviewers highlight its balanced layout and contemporary 38mm size, while some owners find the short lugs contribute to a comfortable wear. The watch features a modern 72-hour power reserve movement and is priced at $3,800. One reviewer notes the lugs are not curved enough, potentially creating a gap with the strap, though owners report the alligator strap softens with wear and some find the watch slightly chunky. A potential frustration for some owners is the power reserve indicator not always resetting to the same position when fully wound. On balance, owners and reviewers rate the Longines Conquest Heritage Central Power Reserve highly for its handsome vintage aesthetic and unique power reserve complication at an appropriate price.

Yema Flygraf Bi-Compax French Air Force

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.
