Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Casio GMA-P2100 for its compact size, with one user noting it fits their wrist when other G-Shocks do not. The watch is described as having a smart look and keeping time with near perfection. One owner finds the GMA-P2100 a suitable size despite considering larger models, and another humorously suggests "P" in the model name might stand for "Pico" due to its small stature. On balance, owners rate the Casio GMA-P2100 highly for its wearability and reliable timekeeping.
The watch is praised for its 200m water resistance and slimmer, sleeker design compared to traditional G-Shocks. Reviewers noted the integrated calculator function. No shared weaknesses were identified.
Owners widely praise the Lilienthal Berlin Lilienthal 1 for its minimalist, art deco-inspired design, clean dials, and satisfyingly finished hands, with some noting its scratch-resistant case and glass. The mesh bracelet is also frequently highlighted as a positive feature. However, there are significant concerns regarding quality control and customer service, with multiple owners reporting functional issues such as timekeeping failures, a difficult or crooked crown, and strap failures. Some owners also find the 42.5mm case size to be large and consider the watch to be a fashion timepiece with better value available elsewhere, particularly at full price. Overall, owners are divided on the Lilienthal Berlin Lilienthal 1, with praise for its design and build quality at discounted prices tempered by recurring issues with functionality and customer service.
