Hamilton Khaki Aviation Air Race AutovsLinde Werdelin Spidospeed Titanium – 3D Movement

Owners widely praise the Hamilton Khaki Aviation Air Race Auto for its legibility and practicality, with some appreciating its countdown bezel and GMT pointer. However, opinions on its design are split, with some calling it a "Frankenstein" and disliking the skeleton hands, while others find the hands suitable for a pilot watch. One owner notes the lume is underwhelming and the 44mm size may be too large for some wrists. The original strap is also described as uncomfortable and prone to water stains. On balance, owners value the Hamilton Khaki Aviation Air Race Auto for its legibility and practical features, despite a polarizing design and some comfort concerns.

The Linde Werdelin Spidospeed Titanium – 3D Movement is praised for its comfortable wearability, with reviewers noting its light presence on the wrist despite a 44mm diameter, attributed to forged carbon and titanium construction. The skeletonized dial is described as dynamic, though some find it slightly busy for time-reading. One reviewer appreciated the dial's design and legibility, while another noted improved, though still less attractive, chronograph pushers compared to earlier designs. The watch features a Concepto automatic movement and is limited to 99 or 100 pieces depending on the specific model, with prices around CHF 21,000 or 11,760 euros. On balance, reviewers highlight the Spidospeed Titanium – 3D Movement's innovative material use and comfortable wearability as its strongest attributes.
