There are literally hundreds.. search on Google for Etsy.. type in custom handmade leather watch band. Stick with 4.9 to 5 star rated sellers of course. I've never really had a problem. Pick out the size style and color and type of weather you want. In addition to Vietnam I've also used some Sellers from Russia.

It depends on which level of ETA it is..Standard, Elaborated, Top, or Chronometer. But then again depending on how much you spent you probably did okay with it being an ETA movement. Having never seen the watch myself I can't attest to the other components. 

I'm sorry I would have to disagree. The only one I would recommend is the Donegan in this particular configuration. They can be had on Amazon for about $50. Make sure it says Donegan there are plenty of look-alikes out there for $10 to $15 that are total crap. Trust me I've learned the hard way.

I have to admit that's a good looking watch.. is that a recent model or a vintage?

Wow $154 for the watch band above? If it was me and I couldn't find what I wanted at a reasonable price I would probably end up at Etsy. There are plenty of individuals for instance from Vietnam who will make a watch band to-your specific order at half the cost. I've used a couple of different ones on several occasions and was completely satisfied. You also may want to check out the watch company called Vario. They have watch bands specifically for that type of watch in the style of a Bund band for their trench watches. 

The watch doesn't seem to have any character it certainly is not an interesting dial. If I had to choose Id choose the turquoise dial over the black one for sure. Their "g-lock"  just doesn't seem to fit on that type of watch and is really only a pale copy of the Rolex glide lock. While it has a miyota movement a lot of the parts are from China. And that crown is way too big. The watch back leaves much to be desired in both form and function.. I'm assuming that will change in production at least I would hope so. Also $420 seems an awful lot to pay for this type of watch. Yes I know manufacturing costs are expensive in Korea but if it was me I'd pass on it. 

Stainless steel Rolex buckles were made by various companies especially back in the late 50s and 60s. So they may have been ereing on the side of caution. But then again there are also a slew of new stainless steel buckles marked with the Rolex distinctions that can be determined as to originality and I think this was so in my case.
