HELM Miyako

HELM Miyako owners widely praise its exceptional value and quality, with multiple reports highlighting its stunning appearance and dial details. The watch is noted for its excellent accuracy, with figures around +1.5 to +2 seconds per day. One owner found the HELM Miyako to be tough and versatile, fitting well on a 6.6-inch wrist. Overall, owners consider the HELM Miyako an amazing value and a great watch, worth the wait for its availability.

Timefactors SMITHS NATO PRS-40 AUTOMATIC

Owners widely praise the Timefactors SMITHS NATO PRS-40 AUTOMATIC for its unique, "badass," rugged, and futuristic design, with some finding its "ugly" aesthetic appealing for its bombproof nature. The Seiko 6R15 movement winds smoothly and operates quietly, and the watch features 100m water resistance and a flat sapphire crystal. The 12 o'clock crown is noted as easy to use by rolling, and the fixed lugs necessitate NATO straps. Some owners report issues with Timefactors' ordering system and customer service, and one found a speck of dust under the crystal, though another noted no imperfections. Overall, owners rate the Timefactors SMITHS NATO PRS-40 AUTOMATIC highly for its distinctive "beater" watch build and unique aesthetic at the price.
