Love the watch

It came in exactly as I expected. Wanted to mod a couple of items to make it my own, but an outstanding watch that even my watch repair place was impressed by.

Expected new bezel to be installed

Lovely watch... but when I ordered the new bezel and bezel insert as a package with the watch, my impression was that these would be installed for me. They were not. I contacted the seller's help line, and was told to install them myself.
Since I'm a beginner at this, I don't have the appropriate tools for getting the new bezel back on, and will have to take it in to a watchmaker.

What a great value watch! This 62MAS homage instantly became my favourite watch in my collection (for context, my collection is filled with watches 3-4X the price). The domed crystal is gorgeous, the sunburst dial is playful and not too busy, the lume is very strong, the bezel action is tight, the case polish/brushing is crisp… only good words from me! And mine is consistently within 1 second a day!!!! Oh and an absolute strap monster too!

Loved my Explorer

Honestly very inmressed with my Namoki Explorer. At this price point its excellent quality is a surprise to me daily.
Pretty sure that im going to get the NMK09 Automatic Field Watch: Khaki . That is the best review of all, going back after the first time. Also the fact that all taxes and shipping is in the actual price you see, no nasty surprises from the taxman or the postman.
