Pre-Built No-Date Submarine Case: Steel, Black YM, Jubilee

+

Our pre-built cases are perfect for watch enthusiasts who are looking to assemble a custom build, but are not interested in the hassle of cutting crowns, lubricating gaskets, and installing sapphire crystals. Only a few steps separate you from finishing your new watch - all you need to do is perform the final assembly. Add the movement, dial, and hands, set the time, and enjoy!

The crown stem has been cut to the perfect length and bonded tightly to the crown. All gaskets will be lubricated before the case is sealed, then the entire case will be pressure tested to 6 atmospheres (~165 ft.) before being thoughtfully packaged and shipped.

Case and crown stem are specifically designed to house Seiko Instruments [SII] NH35a, NH36a, NH70a, NH71a, etc. movements. Purchase includes a professionally assembled case and bracelet only, this does not include movement, dial, or hands.
