What people say

Owners + reviewers, side by side

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

The watch is described as visually striking, legible, and well-made, with a unique case design, sapphire crystal, and a comfortable FKM strap or excellent bracelet with a milled clasp and quick adjustments. Some owners note the bezel's staggered jimping can cause fingers to slip, and the beveled crystal can distort the view of indices. Accuracy varies, with one owner reporting losing 5-10 seconds per day without a winder, while others state it keeps accurate time out of the box. The watch is frequently described as heavy and thick, with some owners finding it too large for wrists smaller than 7.5 inches, although newer models feature an improved clasp for better comfort and functionality. Overall, owners rate the Phoibos Leviathan highly for its striking design and impressive finishing at an accessible price point.

RZE Fortitude GMT

The RZE Fortitude GMT is widely praised for its lightweight titanium construction and durable UltraHex coating, offering exceptional value under $700. Owners and reviewers highlight its comfortable wearability, with a bracelet featuring a quick-adjust clasp and multiple micro-adjustment positions. The Miyota 9075 flyer GMT movement is noted for its accuracy, with one owner reporting -1 to +1 seconds per day, though another source states a range of -10/+30 seconds per day. The watch's design is appreciated for its soul and attention to detail, including a subtle red crown tube indicator and faceted lugs, and its Nimbus Grey dial features a coarse, sandpaper-like texture and fumé effect. A reviewer points out the rotor can be loud and a smaller screwdriver is needed for sizing, while an owner found the GMT hand lume confusing. Overall, owners and reviewers rate the RZE Fortitude GMT highly for its comfortable titanium build, durable coating, and excellent value.
