The Alpina Seastrong Diver 300m Watch is designed to resist the toughest conditions in water. The design focuses on optimal readability. With a 44mm stainless steel case, the aesthetics of the watch are functional and masculine. Firstly, the case features a uni-directional turning bezel in navy blue. This can be used to measure elapsed time for up to 60 minutes. Secondly, the dial is black with applied white indexes. These are coated in super luminova for improved legibility. Additionally, the white hands are bold and easy to read. Finally, a date indicator at 3 o’clock is also a useful feature.

The stainless steel bracelet has a concealed folding clasp with double push button release to ensure the security of the watch. Water resistant to 30 bars (300m), the Alpina Seastrong Diver GMT Watch is suitable for scuba diving. It also has an oversized easy to grip screw-down crown and a see-through caseback. Finally, a scratch-resistant sapphire crystal completes the look.

    From the very beginning of making an enquiry to placing my order for an Oris watch strap I was looked after by Suzie in a professional and friendly manner. I would recommend watch specialists without hesitation to my family and friends. 10/10 thank you for a brilliant experience 😊
