2018 edition!


You are reserving one of our next batch of Hamtun H1 dive watches. The first batch was delivered in 2017 and is currently sold out. We will be making your watch especially for you. Your card will be charged today, and then we will begin making your watch. Delivery is currently scheduled for July 2018, although we will aim to beat this. If you are not comfortable pre-ordering, you should wait until we have stock. Please note that the cost will increase significantly once we have stock, so this pre-order period is the best pricing that will be available.

There are a few small differences in the design of the updated model. These are:

  • Screws in the bracelet have been replaced with pins
  • The blue colour has been slightly changed. We now use the same blue as seen on the Neon range. See a photo of the blue on Instagram
  • Lume has been upgraded


The H1 was the first watch we ever designed at Hamtun Watches, and the white model is our biggest seller ever!

The Hamtun H1 a high spec, affordable automatic dive watch rated to 200m. It has a titanium case, a ceramic bezel, and a Seiko NH35A movement. It comes on either our custom designed silicone or titanium straps and has drilled lugs, making swapping straps a breeze. It features a double domed sapphire crystal. Sapphire crystals are far more scratch resistant than the mineral ones you often see on affordable watches. The crown, used for winding the watch and setting the date/time, is positioned at the 4 o'clock position. This results in a more comfortable day-to-day wear as in this position it's less likely to push in to your hand. When the watch is wound and the time is set the crown screws down tightly to keep water out.

Originally launched on Kickstarter, the H1 was fully funded in just 20 minutes and went on to raise over £160,000 in pre-orders, which have now been fulfilled.

Happy customer (White H1)

Very pleased customer. The watch specs were very adventurous for such a ridiculously low price. Ross ran the project very well and I felt he kept backers updated at all stages. As this was Ross' first KS project, he pulled this off remarkably well and he's clearly listened to customers and has learnt from the project. I look forward to his next project and would definately recommend others to sign up yo his mailing list, to get first views on his next watch.
