The BA111OD Chapter 4 Skeleton Tourbillon T.V.D. is widely sought after as an affordable, visually engaging Swiss-made tourbillon. Owners praise the brand's exceptional quality and the watch's ability to showcase its movement well. Reviewers highlight the open-worked dial and the technical display of the skeletonized movement. Some find the hands hard to see and the case design bland, while others note the audible ticking of the movement and glare on the sapphire crystal. One owner reported a 105-hour power reserve. Overall, owners and reviewers rate the BA111OD Chapter 4 Skeleton Tourbillon T.V.D. highly for its value and intricate, artistic movement presentation.
The Christopher Ward C1 Bel Canto presents a three-dimensional, futuristic aesthetic with an exposed chiming mechanism, drawing comparisons to avant-garde designs. Reviewers note the Grade 5 titanium case, measuring 41mm by 13mm, is finished with fine brushing and polished accents, featuring small, curved lugs. The Cielo blue dial transitions from pale blue to grey, while the Lumière variant offers a luminous sunray pattern and a smoked sapphire sub-dial with a blue Globolight ring that glows blue and green at night, with the hands also glowing green. The Classic variant features a laser-etched guilloché dial with Roman numerals and a blue handset, replacing the original's sunray dial and applied indices. The chiming complication includes hand-finished anglage on visible levers and hammers. The movement is a Sellita SW200-1 base with an FS01 jump-hour or chiming module, regulated to within ±20 seconds per day, with a 38-hour power reserve.
The chiming complication is a standout strength, praised for its clear sound and visual appeal. Wearability due to the 41mm diameter and 13.3mm thickness is a potential concern. Reviewers disagree on whether the watch's complexity justifies its price point compared to other high-end complications.
