A. Lange & Söhne 1815 UpdownvsIWC Schaffhausen Portofino Complete Calendar

Owners and reviewers widely praise the A. Lange & Söhne 1815 Updown for its German artisanal craftsmanship, elegant design, and versatile wearability with both casual and formal attire. The 39mm case is noted as fitting well on various wrist sizes, with reviewers highlighting the depth of the dial and the distinct power-reserve indicator. The manual-wind movement's seconds hand stopping at zero when out of power is considered a handy feature for precise time setting. On balance, owners and reviewers rate the A. Lange & Söhne 1815 Updown highly for its blend of refined finishing and everyday wearability.

The IWC Schaffhausen Iw359002 Portofino Complete Calendar is praised for its elegant presentation of calendar functions with a balanced dial, gold accents, and a fully polished 41mm case. Owners and reviewers note the new complete calendar module with independent sub-dials for day, date, month, and moon phase, powered by the automatic IWC 32150 calibre with a 72-hour power reserve. However, the truncated Roman numerals at 6 and 12 o'clock are a point of contention for some, and one owner finds its 11.8mm thickness noticeable, attributing it to its modular movement construction. Overall, owners and reviewers appreciate the IWC Schaffhausen Iw359002 Portofino Complete Calendar for its elegant dial design and calendar complication, despite some reservations about the hour marker truncation and case thickness.
