Owners and reviewers praise the Airain Watches Type 20 for its faithful vintage design and wearability, with many highlighting the comfortable 39mm case size. The manual winding movement is consistently noted as a pleasure to operate, and the "old radium" style lume is described as pleasing. Some reviewers find the vintage-style sapphire crystal can add glare, and one owner reported a small scratch on the crystal. The movement's appearance is considered less attractive by one source, and the strap hardware required swapping between included straps for one reviewer. Overall, owners and reviewers rate the Airain Watches Type 20 highly for its authentic vintage aesthetic and enjoyable manual winding experience.

Owners widely praise the Studio Underd0g Chronograph's buttery winding action and crisp chronograph activation, with one source suggesting a premium movement version. The 38.5mm case houses a playful, vibrant yellow-to-green dial, described as a cheeky and unique avocado nod. Some owners find the value debatable, with one noting dissatisfaction with the strap and suggesting it may not be worth the price premium over cheaper alternatives. Accuracy varies, with one owner reporting less precision than watches using the Valjoux 7750. Overall, owners rate the Studio Underd0g Chronograph highly for its engaging manual-wind experience and distinctive dial design.
