South Bend 337 and 345 Questions and Database

I have a question about a South Bend pocket watch. The watch is a marked 337 18s 17 jewel. I have a list of serial numbers for South Bend watches, but do not see 337’s shown. If I look-up the serial number it references a 345 18s 17 jewel. The Cooksey Shugart watch guide lists the 337 watch, does anyone have more info on this watch.

South-Bend Model 2, Grade 337...

This is one where there is no clear answer. South-Bend Model 2, Grade 337 movement numbers surface as being within runs of published movement number listings originally assigned to and blocked for the Grade 345 which is desirable due to its damaskeening design and high quality finish.

Most of our interest in the Grade 337 movements is in the fact they are somewhat of an oddity. Although listed in South-Bend catalogues there were never any specific numbers assigned for them. Speculation is the Grade 337 may have been essentially along the lines of "private label" watches made as a way for jewelers to have an item for sale that was not available from a competitor down the street. Those collecting every South-Bend grade consider the Grade 337 a must-have item.

South-Bend 345 number 528324 in marked South-Bend Case...

Thank you Lindell for your expert analysis. I have a few more questions:

Is the South Bend 337 always marked on the movement as a 337? Or, do you have to find a 345 with serial numbers that fall within the range you listed above?

Does anyone know the years that the 337 were produced?

This would be a good topic for the members to list any serial numbers they have for the 337 and note any special markings. The two are that I have are 534279 and 534690 and both marked with 337 within a fancy boxed outline. I have number 534117 but that one is a marked 345 so... the mystery continues.

Note that this example number 534279 does not have the Adjusted markings on it like the 345 like Lindell's picture in the above post. My other example is marked that same way except that one number 534690 also has "Double Roller" located between the case screw and the serial number.

If we get enough examples we may be able to determine the range for the Grade 337 movements. If this range is determined the 345 will have a somewhat lower production total. We could use this topic to post numbers for both the Grade 337 and the Grade 345 that would help narrow it down.


Shown here is 337 movement number 534279

The dasmaskeening is also different than the 345 I have in my collection.

Be sure to read my 337 analysis under the "Help Update the "Complete Guide to Watches" forum.

We need more information on both the 337 and 345 please post yours.

Here is 337 movement number 534279

My marked 345 is number 528635. It is marked as adjusted to 3 positions.

I am starting a list of serial number for 337 and 345 South Bends. Please post your numbers and indicate if they are marked with grade number or not, also marked as adjusted or not,

We have 4 watch serial numbers reported. there must be more out there. Please help us out and post you numbers. Your cooperation is greatly appreciated.

A Friend who also collects South Bend Watches just called. He has a 337 with Serial Number 534767 and a 345 with Serial Number 534195.

This gives a spread of only 84 watches between the last 345 we have listed and the first 337 we have listed.

Here are the numbers we have so far"
528324 345
528635 345
534195 345
534279 337
534690 337
534767 337

You missed the 345 serial number I posted #534117

March 25, 2009, 09:27
Ernie Loga
Keith, You are right. I did miss that one.

Here is the new list ( all are Marked so far):
517220 345
528324 345
528635 345
534117 345
534195 345
534279 337
534690 337
534767 337

If the numbers listed above for grade 337 represent beginning and ending and all the serial numbers assigned in between were for 337 then there were at least 488 grade 337's made.

I also posted this reply under the "Help Update the "Complete Guide to Watches"" forum.

As of this date we have only received serial numbers for 3 South Bend Grade 337 watches. the numbers collected so far are:

534279 337
534690 337
534767 337

This leaves a span of 488 watches if all of the numbers between the lowest and the highest were used. We need more serial numbers reported as this is not enough numbers to make any kind of judgment call.

My guess is if the 337 were simply a private label watch then we are going to find some grade 345's intermixed between the lowest and highest 337 numbers we have recorded so far.

Please Report more 337 and 345 numbers to us. If you don't want to post the numbers you can email them to me at:

Looking back on old posts I found this post from Andre showing a 345 with serial number of 517443. Another number for the list.

April 01, 2009, 18:13
Ernie Loga

I found that yesterday when I was looking back. I added it to our list but I didn't repost an update because it has not changed or narrowed down the beginning or ending of the 337.

As of this date we have registered only 6 grade 345 watches and 3 grade 337 watches. If this is all there is then these watches are even more rare than we initially expected.

There have been 533 views of this post but no one has added any new watches or emailed me with any new watches since April 11, 2009.

We sure wouild like to add to this list so we can make a solid recommendation to have the Complete Price Guide of Watches updated.

If you have a South Bend 345 or 337 watch please post that infomation and help us out.

You guys are doing great!

Here are two more confirmed Grade 345 sightings with attribution links...

>>> 534385 -- Adjusted to 3 Positions

>>> 534946 -- Adjusted to 3 Positions

Inserting these numbers into Ernie's list will show we have a trend developing!

With Lindell's two 345 the count looks like this:

517220 345 Marked
517443 345 Marked
528324 345 Marked
528635 345 Marked
534117 345 Marked
534195 345 Marked
(84 unknown watches)
534279 337 Marked
(106 unknown watches)
534385 345 Marked
(305 unknown watches)
534690 337 Marked
534767 337 Marked
(179 Unknown watches)
534946 345 Marked

This adds a new dimension. There is now a confirmed 345 number 534385 in the middle of the 337 production. There are 84 unknown watches between the first 337 we have reported and the previous 345 that was reported. There is 106 unknown watches before the next 345 reported.

In the last set there are 179 unknown watches,

All of the 337 grades reported to date have been from Production Run 4.

I have two to report.

The first is SN 534080, Marked "345". That extends the range of the known list for the 534,000 downwards. I would guess (but not bet, because these serial are seriously goofy), that 534001-534080 are all Grade 345's.

Second is SN 534263, Marked "345". That extends the range of known 345's upwards towards the first known 347 by some 60+ numbers. I hope some people are still looking out for these watches. I think a few more data points are needed to make a good guess at where the limits are for the ranges.

I am focusing here on the 534001-535000 range. Now it looks like this, the ones I added are bolded:

534080 345 Marked
534117 345 Marked
534195 345 Marked
534263 345 Marked

534279 337 Marked

534385 345 Marked

534690 337 Marked
534767 337 Marked

534946 345 Marked

And here some pics of the more interesting of the movements...

Thanks Frank.

We are getting closer but we are still a long way from any definitive list that we can make a valid determination with.

Does anyone in IHC 185 have any additional grade 345 or 337 South Bends to report?

It just gets better and better.

We received this eMail from a gentleman who did a search regarding his South-Bend 337 and found this topic...


Lindell V. Riddle, President

I have come across the South Bend discussion concerning the 18S Grade 345 and 337.

Recently I acquired S/N 534869 17J LS OF marked 337, gold lettering on the movement,
marked Double Roller. It has a white SS Arabic Dial with red 5 minute increment numbers.

It is housed in a Keystone Watch Case, Silveroid, S/N 858790.

Hope the information is useful.

On online databases the watch is identified as a grade 345.

And the beat goes on!

Another marked 345 has shown up, number 528807 with single-sunk dial and marked "Adjusted 3 Positions" on the barrel cover.

The pattern of these "mixed-runs" is falling into place, there is no longer any doubt.

then numbers 517701-518000 were Double-Roller and Second Run.
From then on all 345 and the 337 movements were Double-Roller.)
