[SalesForce] Ampscript FOR Loops results to retrieve product using a second Loop

I have 3 salesforce objects:
– PersonAccount
– MyWatches (Fields:PersonAccountId, ProductId, Status = Owner) – contains the list of watches bought by the PersonAccount
– Product2 (Fields: Series) – contains product details

PersonAccount is linked to MyAccessories and the MyAccessories records contain a Product ID (lookup to the Products object).
A PersonAccount can have multiple MyAccessories records.

I have used a loop to retrieve all the accessories purchased by the PersonAccount. So far so good.

%%[VAR @SubscriberKey 
SET @SubscriberKey= _SubscriberKey 
IF NOT EMPTY(@Subscriberkey) THEN 
SET @ContactTable = RetrieveSalesforceObjects("Account","Id","Contact_ID__pc", "=", @SubscriberKey) 
SET @ContactRow = ROW(@ContactTable,1) 
SET @PersonAccountId = FIELD(@ContactRow,"Id") 
ELSE 
ENDIF]%%
    %%[IF NOT EMPTY(@PersonAccountId) THEN 

SET @MyWatchesTable = RetrieveSalesforceObjects("My_Watches__c","Product__c","Person_Account__c", "=", @PersonAccountId,"Status__c","=", "Owner") 
SET @rowCount = RowCount(@MyWatchesTable) 
IF @rowCount > 0 THEN 
FOR @counter = 1 to @rowCount DO 
SET @MyWatchesRow = Row(@MyWatchesTable, @counter) 
SET @Product = Field(@MyWatchesRow,"Product__c") ]%%

%%=v(@counter)=%% Product: %%=v(@Product)=%% 

%%[ next @counter ]%% 
%%[ else ]%% 
No records found 
%%[ endif ]%%

%%[ENDIF]%%

As you can see from the image below it retrieves multiple product Ids but only the series associated to the last product Id.

I need to retrieve the value in the Series field stored on the Product2 object associated with the products the PersonAccount has purchased.

I tried to use a second LOOP but it only retrieves the series for the last purchased product id.
Is it possible to retrieve it for all?
The end goal is to then use the series retrieved to tick multiple checkboxes on the page.

    %%[ VAR @ProductTable, @productCount, @productcount 
    SET @ProductTable = RetrieveSalesforceObjects("Product2","Series__c","Id", "=", @Product) 
    set @productCount = RowCount(@ProductTable) 
    if @productCount > 0 then 
    for @productcount = 1 to @productCount do 
    VAR @ProductRow, @Series 
    set @ProductRow = Row(@ProductTable, @productCount) 
    set @Series = Field(@ProductRow, "Series__c") ]%% 

Prod %%=v(@productCount)=%% Series: %%=v(@Series)=%%

 %%[ next @productCount ]%% 

 %%[ else ]%% 
 No product found 

 %%[ endif ]%%
