It is a Helson Sharkmaster 300 watch. I am a Korean On-Line watch reviewer, and I bought it in June of 2023 to review for Korean watch review.   But I really liked the watch, so I decided to keep it rather than selling it immediately.

As you can see from the photos, it is very sparingly used.  Probably less than a month of total wrist time.

I am selling it because I want to buy 2024 Tudor Mono-Chrome 41mm.

As you can see, it is very clean. It has ETA-2824 movement which is very tough to get nowadays.  This watch is keeping time remarkably well and the lume is out of the world.

I put all the links back, so probably it will fit more than 8” wrist.

If you know Helson Sharkmaster, it is a very sought after watch and it has been out of stock forever.  Helson told me that they are having a very difficult time getting ETA movement and refused to use SW movement for their Sharkmaster 300.

This watch is as perfect as it can be.  Everything works great as it should.  Also, you will receive the watch within a week.

I am a private watch collector & on-line reviewer, not for business, and I frequently sell my own watches here on eBay and I have top-rating on all my sales.

Finally, sorry but I cannot ship internationally, just within USA states. CONUS ONLY Shipping.  I cannot sell to buyers that have no feedback.  At least the buyer must have 8 positive feedback to bid and buy.  Sorry but I had a few bad experiences before. 

Thanks for understanding.
