Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Bulova Black Dial EPDM Rubber Strap Series X 98B358 for its reliability and durability, noting its ability to withstand daily wear, accidental drops, and swimming. The quilted dial texture is a specific point of appreciation. However, owners are divided on the stock straps, with one owner expressing a strong dislike and considering strap replacement or a bracelet. The watch features a quartz NN50 movement, a 300m water resistance rating, and a 45mm case. Overall, owners rate the Bulova Black Dial EPDM Rubber Strap Series X 98B358 highly for its robust build and attractive dial, though strap preference varies.
Owners widely praise the Certina DS-X GMT for its functional GMT complication, rugged build, and value, with one owner noting its $269 price as a good deal for the well-made quality. Reviewers highlight its vibrant, fun design as a departure from typical offerings, and its practical dual-bezel system. Some owners find the quartz movement a no-brainer for accuracy and lower cost, while others prefer automatics and note the MSRP can be high. The inner 24-hour bezel's 90-click action is criticized for misalignment, and lume is described as functional but not exceptionally bright. One owner reports the bracelet clasp rattles. Overall, owners and reviewers rate the Certina DS-X GMT highly for its functional GMT complication and value at its price point.
