What people say

Owners + reviewers, side by side

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

IWC Schaffhausen Iw501705 Portugieser Automatic

Owners widely praise the IWC Schaffhausen Iw501705 Portugieser Automatic for its timeless design, stunning dials with depth and brilliance from multiple lacquer layers, and pure class. The 42.4mm case size is noted as fitting well for many, and the in-house Calibre 52011 movement offers a 7-day power reserve. Some owners appreciate the pocket watch aesthetic and the suitability of alligator straps over steel bracelets for its dressier vibe. However, some owners wish for smaller case size options, with a preference for 36-38mm. One owner reported the watch stopping after 13-14 hours off the wrist, contrary to the claimed power reserve. There is also a community observation that IWC Portugieser Automatics can depreciate significantly. Overall, owners and reviewers rate the IWC Schaffhausen Iw501705 Portugieser Automatic highly for its stunning dial finishing and classic aesthetic at its price point.

NOMOS Glashütte Lambda rose gold

Owners and reviewers widely praise the NOMOS Glashütte Lambda rose gold for its thin 8.9mm case, Bauhaus dial with precise sub-dial spacing, and the artistic presentation of its 84-hour power reserve. The in-house DUW 1001 movement is highlighted for its Glashütte finishing, including a 3/4 plate, gold chatons, hand engraving, and blued screws. Some owners find the 42mm size wears large due to the thin bezel and dial proportion, and one commenter described the power reserve display as "a bit weird." The price is noted as $17,800 to $20,000, with one owner suggesting a secondary market purchase to minimize financial loss. On balance, owners and reviewers rate the NOMOS Glashütte Lambda rose gold highly for its refined wearing experience and the technically and aesthetically impressive hand-engraved movement.
