This in my opinion is a very rare pristine example of a 60's Gruen Precision Swiss Made 510 D Mechanical Movement Men's Wristwatch Time Piece with Date Calendar.  What Makes this example further outstanding, is that I sourced a NOS Two Piece Gruen Signed Strap and a gorgeous NOS Spiedel Guilloche Stretch Bracelet that makes this piece truly Pop.  Take a look at the pictures.   Also included is its original Watch Box.  If you are a Gruen Collector or Avid Collector of Mid Century American Manufactured Watches in general, Get this one.  It's in rare incredible condition.  If you have any questions, just ask.  If you need further pictures, please let me know.  This is my favorite Gruen except for my Dad's with the Diamond Dial.   I just want it to get it to the next generation of collector and be worn proudly.  It's an attention getter.

As you can see, I am an avid Vintage American Watch Company     You will see by the ones I have recently sold, that the collector./buyer is highly satisfied.   I ask more for my pieces, because of my keen sense of condition, originality and the care I take with each, unlike many you will see on here.  In fact, the entire case and case back, show very little wear and this watch was well taken care of prior to my acquisition five years ago.    I take detailed   quality photographs, however, if you require any Others, or have any questions, please feel free to contact me.

Time is accurate, movement is quite excellent condition as well. 
All sales are final and no warranty is implied or expressed.

I take great care in the way I prepare a watch from my collection for shipping.  I always include a complementary Watch Cloth as well.  Every watch is sent fully insured.  With more  expensive watches I ask for signature confirmation to protect you.  You can let me know if you'd like that with this one.  I've never had a problem with delivery.  Well, one but that was bungled by Ebay International Shipping.

So go ahead and BuySumTyme, I  believe you will be very happy you did.  Thank you for your consideration. 
 
Just some Background:

As you will note in my other listings, my passion for watches began as young boy in 1970.  My Dad's Childhood Friend Russ Neglia became a professionally trained Watchmaker and joined  Bulova in the early 50s in their Woodside Headquarters.  Later on in the Early 70's he had his Own Bench right on  the Lower East Side Diamond District; Delancey and Orchard Streets Both Dad and Neil grew in the A, B, C's. .

There is where it started for me as a 10 year old in Wonder.  Dad bought many Watches From Neil and for me it was fascinating; especially when he would let me sit next to him as he worded on a particular watch.  Then it truly took off when my Mom and Dad Brought my brother and I while they were away in the Bahamas, and we received a beautiful Seiko 6137 Automatic Wind with this gorgeous Orange Dial.  I only wish I had it today, because I can't seem to find one like it.

My collection began it earnest upon semi-retiring 15 years ago.  Mostly the late , great American Titans.  I am not a flipper though on the rare occasion I have flipped a watch I decided not to add. 

All Sales are Final. Generally because these are vintage, very old, I don't accept returns, but by all means contact me.  I have 100% positive Feedback for a reason.  I've sold a few timepieces in the last two months, so there is recent feedback, but go back to the Seller Feedback.  No Warranty is Expressed nor Implied.  Thank you so much for your consideration.
