I've had difficulty finding a nice alligator 19MM blue band to go with my Seamaster Pro. The Seamaster has a 19MM lug, but the best band I can find is a 20MM band. Is it possible to use the 20MM band if I use an Omega spring pin? Has anyone had success doing this?

 

I once did this with my watchmaker. He cut just a tiny bit from the edges of the band to make it fit properly

I also wanted a blue gator, and 20mm was the only choice back then. I think you will not have any problem either.

 

You can also try using smooth tipped pliers to compress the 20mm strap widthwise (at the lug end) by a few mm and hold for several seconds. This should compress the strap enough to allow you to easily fit it in a 19 mm lug.

 

It's been my experience with crocodile and alligator straps that shrinkage occurs after a period of time / usage.

 

I bet you can pay through the nose and get one from Omega. I was quoted $300 and some change for an 18mm Omega blue alligator strap or you can try one of these. https://www.ebay.com/sch/i.html?_fr...&_sacat=0&rt=nc&Band%20Width=19mm&_dcat=98624Purchases made through these links may earn this site a commission from the eBay Partner Network

 

Which 1990s SMP has 19mm lugs exactly? I can’t think of one.

 

Thanks everyone. That is good info. I can post of pic of the watch so you can see. Problem is I can only measure using measuring tape. I don't have a caliper. It reads 3/4" which I believe is 20MM.

 

sorry.. 3/4" is 19.05MM

 

Here's a pic of the SMP.

 

Thanks. I went aftermarket and was considerably cheaper. the SMP has blue numbers on the bezel the same color as the strap so hopefully it looks good.

 

And it’s on...

 

20mm band on a 19mm lug watch. It was a tiny bit snug but loosened up quickly. Seems very secure

 

Looks great. And it is secure.

 

Thanks. I like it.

 

That strap color matches your watch perfectly!

 

I was worried it was brighter blue. Ended up working out. Thanks

 

That’s a mid size SMP. Lugs are 18mm. As I said above, no SMP has 19mm lugs.

 

One of the Hodinkee 18 mm aged green leather straps would be great on that - either the aged moss or aged hunter green) To match those plots

Heres the darker hunter green on a few of mine

 

Thanks. I like the dark green strap like the one you have. That strap in aged blue would be nice also. I went with the blue because the numbers on the bezel are blue.

 

I found out yesterday that this is a 2000 model. I read and responded to your point, but it still measures as 3/4" which is 19mm. However, I do not have a caliper so I am relying on measuring tape. If it is, as you say, 18mm, then the 20mm band was able to fit nicely.
