    Absolutely superb, the production of this is high quality stainless steel in perfect condition - exactly as pictured and possibly better than I had hoped for. It fits exactly with my Marinemaster bracelet and really looks the part. Great price and no hesitation in recommendation.

    Great Seiko bracelet upgrade!

    This is a great way to upgrade your Seiko bracelet with an on-the-fly adjustable buckle. Pretty much identical in all aspects to the one on my MM300 SLA019J1 (circa 2018/19) with only a few microscopic differences. This is a great item. I don't think you will be disappointed. Price is very fair for what you get. The images show the buckle on my Sumo beside an all original MM300 buckle.

    Great Genuine Seiko Ratcheting Clasp!

    While this clasp is specific to only a few Seiko watch models like the MM300 and the Velatura, it will also fit other Seiko dive watch bracelets. In my case, I installed it on my Gen. One Orange Seiko Monster watch replacing the folding dive extension. It was a drop in replacement! Two spring bar pins were removed to swap out the original folding diver extension with the ratcheting clasp. Perfect fit! Adjust on the fly for daily wear, wrist swell, over an outer garment, over a dive suit or neoprene cuff of a cold water wading jacket. very easy to adjust. This should be a standard or optional clasp for all Seiko dive watches. I will be buying more and replacing or adding this dive extension clasp on my other Seikos.

    excellent service! Top product!

    Great clasp, the micro adjustment makes it possible to ease up or tighten the watch, or wear it over a wetsuit.

    Marine master clasp

    I purchased off eBay this clasp. And is of reasonable quality. I compare this with a strapcode strap and clasp. And the quality is not as good. The sides of the marine master clasp are brushed and as I bought for my Seiko sumo they were originally polished. This is not too much of a problem.. as I bought a polishing wheel and wax. The actual clasp itself is very comfortable. And the best part is that you can adjust to give slight expansion when hot. And is nice to have a branded clasp with Seiko emblem. One of reasons didn't buy strapcode bracelet clasp. Hope this helps potential buyers.

    Great Strapcode upgrade

    I have a Samurai on a Strapcode Hexad bracelet. I was never really happy with the V-clasp that came with the Strapcode, and also wanted some more adjustability. The MM300 clasp fits perfectly and feels much more secure. The metal can be polished if desired.
