Editor's Note: At $89.00, this case offers a significant aesthetic upgrade that punches well above its weight class for custom watch builds.

Performance & Build Quality

The 316L stainless steel construction feels substantial and offers excellent resistance to the daily wear and tear I expected. The machining is impressively clean for the price, with sharp lines and a finish that mimics much more expensive luxury pieces.
