The Glycine Men's Combat Sub 42mm Automatic Watch GL0189 is praised for its wearability on smaller wrists, attributed to its thin 10.4mm case and inward-bending lugs. Owners report its lume lasts longer than a Seiko SKX007's, though one notes the 6 o'clock lume appears slightly underapplied. The watch is noted for its sharp looks and solid build, with one owner wishing the bezel pip had a triangle. The Glycine Combat Sub 42mm Automatic Watch GL0189 is available at significant discounts, often found around $300-$330. Overall, owners rate the Glycine Men's Combat Sub 42mm Automatic Watch GL0189 highly for its comfortable wearability and value proposition at its discounted price point.
Owners widely praise Resco's customer service, with one owner noting their watch was repaired quickly and affordably after a severe accident, and another appreciating the brand's veteran-owned roots and Navy Seal heritage. The cases are described as strong, and the watches are considered durable and suitable for outdoor activities. One owner specifically mentions the cool dial design with small 0.2-second indices and a trident second hand. However, one owner reported rusting issues on the case by the time and date adjusting screw, which the company stated is normal and may require cleaning. Another owner felt Resco watches are not great value for money given their ETA movements and price. Accuracy figures vary, with one owner reporting a loss of -9 seconds in 7 days while the watch was breaking in. Overall, owners value Resco Stainless for its durability and strong customer service, despite some concerns about value for money and occasional case maintenance.
