What people say

Owners + reviewers, side by side

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

Tudor Black Bay Chrono S&G

The Tudor Black Bay Chrono S&G is widely praised for its bold, vintage-inspired two-tone design, solid modern build, and attractive price point. Owners and reviewers highlight its well-made bracelet, T-fit clasp, and compelling styling, with some noting its unique, muted gold tone that is less flashy than other gold watches. One owner reported excellent timing accuracy of +/- 1 second per day. The Tudor Black Bay Chrono S&G utilizes the MT5813 movement, a modified Breitling B01, offering a 70-hour power reserve. However, some find the 45-minute chronograph register less practical than a 60-minute counter, and the use of gold capping on the bracelet and bezel is a point of contention for some, with one user also noting faux bracelet rivets as a detractor. The watch's thickness and lug structure are also cited as potential drawbacks for wearability on smaller wrists.

Yema Rallygraf Meca-Quartz II

Owners widely praise the Yema Rallygraf Meca-Quartz II for its cool retro 70s vibe, faithful reissue of a thin vintage design, and excellent build quality for its price, with particular commendation for its tactile pushers and top-notch Milanese strap. The watch is noted for its substantial, weighty feel and well-aligned indices, and the Seiko VK64 meca-quartz movement provides a sweeping chronograph hand. However, some owners find the meca-quartz ticking not very smooth, the left subdial a "useless" 24h indicator, and the watch overpriced compared to similar models. Several owners report disappointing alignment issues with indices, and one owner experienced the dial rotating slightly when chronograph pushers are depressed or when adjusting the time, with these issues not resolved during service. On balance, owners rate the Yema Rallygraf Meca-Quartz II highly for its retro styling and perceived value, despite some recurring quality control concerns.

From video reviewers

The watch's vintage-inspired design and value at its price point are consistently praised. The meca-quartz movement is mentioned as a feature by multiple reviewers.
