|description=The Rolex 3696 is a 1940s Oyster Perpetual Bubbleback documented in pink gold and steel construction, part of the two-piece-case generation that succeeded the original 1933 Bubbleback. Christie&amp;#039;s has catalogued one example, case 302833.&lt;br /&gt;

&lt;br /&gt;
The 3696 is a 1940s Rolex Oyster Perpetual Bubbleback documented in a mixed pink-gold-and-steel case — the bi-metal construction Rolex offered across several Bubbleback references as a lower-cost alternative to solid gold without dropping to plain steel. Christie&amp;#039;s catalogued one example, case number 302833, in a mixed-lot vintage watch sale alongside several 3131 Bubblebacks in solid and pink gold from the same decade.&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;Source density note.&amp;#039;&amp;#039;&amp;#039; This reference is documented from a single located auction record — no dedicated editorial review or collector guide singles out the 3696 specifically. The broader Bubbleback family history below (case architecture, movement generations, dial vocabulary) is documented from general Bubbleback sources and is not 3696-specific except where stated.&lt;br /&gt;

== Where it sits in the line ==&lt;br /&gt;
&lt;br /&gt;
&amp;quot;Bubbleback&amp;quot; is a collector nickname, never an official Rolex designation, for the family of Oyster Perpetual references built from 1933 through the mid-1950s around a protruding, domed caseback needed to house the early automatic winding rotor. The first Bubbleback, reference 1858, used a three-piece case; Rolex moved to a simpler two-piece case design in 1936 with references 3131 and 3132, and the 3696 belongs to that later, two-piece-case generation based on its case-number range and its appearance in the same Christie&amp;#039;s lot grouping as several 3131 examples from the same decade.&lt;br /&gt;
&lt;br /&gt;
Anthony Traina, writing the Bubbleback family history for Hodinkee, calls the reference range &amp;quot;nearly impossible to catalog comprehensively&amp;quot; despite specialist attempts — Colin A. White&amp;#039;s &amp;#039;&amp;#039;The Vintage Rolex Field Manual&amp;#039;&amp;#039; documents no fewer than 172 distinct Bubblebacks once metal and dial variations of otherwise identical reference numbers are counted separately. The 3696 sits inside that wide, only partially catalogued range as one bi-metal configuration among many.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span id=&amp;quot;production-outline&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;
== Production outline ==&lt;br /&gt;
&lt;br /&gt;
Rolex offered Bubblebacks across solid steel, solid 9ct/14ct/18ct yellow or rose gold, and mixed metal cases combining a gold bezel or caseback with a steel case body — the configuration documented for the 3696. The single located example, case 302833, is undated beyond a general 1940s attribution in the Christie&amp;#039;s catalogue entry, consistent with the reference sitting inside the two-piece-case generation that ran from 1936 into the postwar years.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span id=&amp;quot;movement-notes&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;
== Movement notes ==&lt;br /&gt;
&lt;br /&gt;
Bubblebacks as a family ran a sequence of self-winding, water-resistant calibers scaled to the automatic rotor and the Oyster case&amp;#039;s sealed construction — caliber 520 powered the first reference, 1858, in 1933, with later calibers powering the two-piece-case generation the 3696 belongs to. No caliber has been independently confirmed for the 3696 specifically; the Christie&amp;#039;s catalogue entry for the documented example does not list a movement caliber.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span id=&amp;quot;case-bezel-crystal-and-crown-notes&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;
== Case, bezel, crystal, and crown ==&lt;br /&gt;
&lt;br /&gt;
The documented 3696 is a mixed pink gold and steel case — likely a steel case body with gold bezel, crown or caseback elements, following the same bi-metal cost-reduction pattern Rolex applied across several Bubbleback references rather than offering every configuration in solid precious metal.&lt;br /&gt;
