  • Make sure the crown is pushed in.
  • Rotate the crown in a clockwise direction for 20-30 full rotations .This will provide the watch with enough energy to operate solely off the movement of your wrist.
  • If the watch is not worn for 15-20 hours this process will need to be repeated.

Our Seagull watches come with a 41mm case and a large opening that permits an excellent view of the skeleton movement – and a fascinating opening into the world of mechanics.

    Robust, looks and feels more expensive than it is.

    Posted by Almanzo McConkey on 31st May 2023

    I've been wearing this watch every day since I ordered it over 2 months, and it still looks as pristine as when I bought it. The rubber strap is comfortable enough that I forget I'm wearing it, and is small enough for a slender wrist like mine. I had a few questions about the timepiece, which John B answered very helpfully by email within a day. It's the first time for me that looking at the time has been relaxing, and I feel good wearing it. Thank you, John B!

Sapphire glass is the premier league when it comes to watch crystals. It is brilliant, highly-transparent and extremely strong in terms of its structure. Its most outstanding feature is its excellent resistance to scratches.

Fitted with green lume markers for  nocturnal visibility.

316L is the superior choice for high corrosion and high temperature applications. Since 316L contains less carbon than 316, it has better intergranular corrosion resistance, meaning its welds won't decay, unlike with 316 stainless steel.

Water resistance actually refers to how much pressure the watch can handle and it’s typically measured in atmospheres (ATM), bars, meters, or feet.
