I'm not sure that the numbers matter that much as far as the percentage fall post Christmas is concerned but we will see.
From the AFR article, Mark said;
"Being a new market, it's hard to predict what sales will be but, based on the current run rate, we'll be out of inventory again by about mid-February so we have already planned another manufacturing run in February,"
...and FS0010 was worried about a write off of stock?

From the article;
"The business had hoped to hit the 20,000 mark by the start of the year, but retailer JB Hi-Fi underestimated how many of the devices it would sell and ran out a few days before Christmas. The smartwatches are also sold through New Zealand telco provider Spark.
MGM Wireless chief executive Mark Fortunatow was confident the company would sell out of its 23,000 devices by the time children return to school, with sales already picking up."

It looks to me that from what Mark is seeing, there won't be much of a drop off post Christmas (if any at all).
