The Boettger is not a brand new model for Spinnaker, and it smartly borrows from the very niche and rare Sinn 809 with its unique markers adhered to the underside of the sapphire glass. But this time around, the Boettger gets a brilliant new integrated Nitrile Butadiene Rubber strap. Not only does it look flawless as the watch lugs taper and transition into the strap, but the strap is also a secure diving companion for the watch while sitting beautifully on the wrist. The watch is still powered by Miyota 9015 automatic movement and has a tough and view-friendly sapphire crystal with AR coating. It’s also no joke when it comes to the depths, with a full 300 meters of water resistance. The model is limited to 500 units in each of the three different colors and is available now.
