AVI-8 Spitfire Lock ChronographvsTAG Heuer Formula 1 Chronograph faceted/octagonal Speed chronograph 43mm (crown-guard case)

Owners widely appreciate the AVI-8 Spitfire Lock Chronograph's compelling design, drawing inspiration from Supermarine Spitfires with details like a prominent crown and rivets, and find the build quality excellent for the price. The watch features a 42mm stainless steel case with curved lugs for wearability, a bi-compax layout with subdials for elapsed time and a 24-hour scale, and black lume that glows green. Some owners note that AVI-8 watches offer something different and are decently well-made, though not of insane quality, and one reviewer found the included leather strap and bracelet to be the weakest aspects. On balance, owners and reviewers rate the AVI-8 Spitfire Lock Chronograph highly for its striking design and good value at its price point.

Owners widely praise the TAG Heuer Formula 1 Chronograph faceted/octagonal SPEED chronograph 43mm (crown-guard case) for its cool design, solid construction, and versatility as a daily watch, with many finding it wears smaller than its 43mm case size and offers good value. The stopwatch function is noted as fun, and the double date windows are considered a cool feature by some. However, a significant portion of owners express reservations about the quartz movement, deeming the price point too high for a battery-powered watch, and some find the plastic case design reminiscent of a child's watch. One owner experienced a loss of timekeeping accuracy after several years, and difficulty with battery replacement is mentioned. The fixed bezel is seen as a drawback by one owner, and the resin straps are noted as prone to splitting.
